Soylent Amino Acids and Training


#1

I’m wondering, what Amino acids recommended in soylent? L-amino acids or D-amino acids? is it good to have all 22? especially for training.
it’s in swedish, but look on the amino profiles

Just came across this opinion ( a Guest article by Laura WHITE ) , so it is maybe a good starting point here as an answer . ( The " high quality proteins " could also be taken in the form of ( vegetarian / vegan ) supplements http://michaelbluejay.com/veg/protein.html )

http://thedetoxspecialist.com/blog/detox/discover-the-immense-benefits-of-detoxing/

After a workout it is important to consume a carbohydrate and protein blend in order to replenish glycogen stores and replace muscle protein which will be catabolised during the workout. Within the protein content it is important to consume all 8 essential amino acids which can be found in high quality proteins such as lean meats, chicken, nuts, egg whites, etc as these are not naturally occurring within our bodies.

After completing a HIIT workout (high intensity interval training), it is extremely important to consume these nutrients as soon as possible post workout, as there is a window of around 2 hours post exercise where your body is most responsive to food intake – i.e. protein and carbohydrate stores can be replenished to a greater extent. Also, high intensity workouts burn the most calories up to 24 hours afterwards through a process known as EPOC (excess post exercise oxygen consumption).

Proteins are recommended to be 20% of your daily food intake, and more than this when we exercise. It is recommended by nutritionists that your protein intake should be split 50/50, with half being consumed 30 minutes before your workout (to limit muscle catabolism/breakdown) and the other half being consumed 30 minutes post – to provide the raw materials for muscle building. <

These lines I found in a book " RIGHT HAND , LEFT HAND , The Origins of Asymmetry in Brains, Bodies, Atoms and Cultures " By Chris Mc Manus (2002). His website is : http://www.righthandlefthand.com/ .
A rather fascinating story : humans are made of L-amino acids and of D-sugars ! So , as I understand it , it would be better to use L-amino acids for supplementation , since D-amino acids would be not be used by the body .

Amino acids come in 2 different forms called L ( for laevo , or left-handed ) and D ( for dextro , or right-handed ) . Every time an amino acid is added to the growing protein chain , it is an L-amino acid .The genetic code and the entire translation machinery are based only on L-amino acids .As far as we can tell , that is true for every organism on this planet . Such a complete depence on L-amino acids raises many fundamental questions for biology . Amino acids are not the only place where biochemical asymmetry can be found . The sugars that make up our body , such as glucose , are also found in just one form , this time the D-form . Again , it is a perplexing truth deeply in need of explanation

Update Oct 27 , 2013 . Just found this

Life as we know it builds its proteins primarily from the same 20 amino acids, although there are many other amino acids that might have been utilized. While it is important that the collection of amino acids used in proteins includes a sufficient number of small, large, hydrophilic, hydrophobic, and charged amino acids, the exact identities of the amino acids in each of these classes may not be critical. Moreover, the amino acids utilized for protein synthesis by familiar life are all L-amino acids, and there is no reason to think that D-amino acids could not have been utilized instead.

In chemical processes, left- and right-handed molecules are generally formed in equal amounts, unless chiral reagents, catalysts, or surfaces are present to introduce a bias. Also, some organisms may synthesize the same chiral compound in different enantiomeric forms (e.g., bacterial peptide toxins). For the formation of regular structures when these monomers are assembled, however, it is generally more efficient to have the same handedness in all molecules. Thus, 100 percent of amino acids in terran proteins have the same absolute spatial relationship of the amino group, the acid group, and the side chain distinctive for the amino acid and are all designated “L”. Likewise, all of the sugars in nucleic acids have the opposite spatial relationship and are designated “D”. Enantiomeric excess (also called chirality, or handedness), the predominance of one enantiomer over the other for a given assembly of atoms, is therefore believed to be a universal feature of chemistry characteristic of living systems.


( Ashutosh (Ash) Jogalekar )

The same principle applies to chemistry. For instance the supreme being would never have been able to tell us why there are only twenty amino acids, why there are alpha amino acids instead of beta or gamma versions (which have extra carbon atoms), why amino acid stereochemistry is L while sugar stereochemistry is D, why there are four DNA bases with their unique structures, why nature chose phosphates (although Frank Westheimer comes close), why a given protein folds into only one unique functional structure, why water is the only solvent known to sustain life, and in general why the myriad small and large molecules of life are what they are. In retrospect of course one could provide several arguments for the existence of these molecules based on stability, function and structure but there is no way to predict these parameters prospectively.

Update Oct 29 , 2013 .Found this on a forum : http://www.reddit.com/r/askscience/comments/opnjl/why_do_all_species_use_only_l_amino_acids/

Question :
Why do all species use only L amino acids ? I learned in biochemistry that all living organisms only utilize the L configuration of amino acids, but if we were to somehow inject the D configuration into an organism could it utilize it and make proteins from it?

Answer ( an example ) :
No, it could not utilize the D conformation because the D configuration would actually make a completely different product. They are sometimes used in proteins, though. The truth is, we really don’t know why the L is preferred in the body. It is theorized that the L configuration is slightly more stable than the R, and has been naturally selected to be the configuration of choice. It is also theorized that having all the amino acids in one conformation makes it easier for the body to produce proteins, rather than two.

Also this one on the forum : http://www.reddit.com/r/askscience/comments/zuddf/is_the_l_amino_acid_excess_due_to_d_amino_acids/

Question :
Do the laws of physics always show complete symmetry between left and right? I’ve read recently that parity is in fact not conserved, and that electrons are ‘left-handed’. Does this mean that L and D amino acids are not true mirror images (since the electrons handedness are not mirrored), thereby have different properties and if so, can this explain why we have an L amino acid excess over D? Can anyone explain this a bit, or add some insight? I find it very interesting, but don’t really understand the physics. Thanks

Answer ( an example ) :
Why are amino acids L? (this is my memory don’t know the current popular theory)The reason amino acids exist predominantly in the L configuration biologically has to do with efficiency, and production of proteins. A protein with a random mix of D and L would not be the same as all D or all L; so biologically it makes sense to just use all L or all D so we consistently have functioning proteins and are not wasting lots of energy on junk. The reason it turned out to be L everywhere is because we all evolved from the same ancestor and that was the luck of the draw most likely.

Why is there no particular chemical reason for L? molecular geometry does not keep track of electron spin only the 3 dimensional arrangement of atoms in space. Second it is just as easy to make D amino acids as L amino acids if you were to synthesize them with a catalyst that doesn’t select for stereochemisty, synthetic production of amino acids is almost always a 50/50 mix. Finally I never heard of electrons being left hand in fact electron spin can change and in atoms there are spin pairs.

Taken from the book “So shall we reap” ( 2003 ) by Colin TUDGE
http://www.colintudge.com/

Twenty-something amino acids are know in nature , of which about twenty are found in the human body . About a dozen of these latter are conventionally said to be “non-essential” , which does not mean that the body does not need them . It simply means that they do not need to be present in food , because the body is able to make these “non-essential” types from other amino acids that are present . But eight are said to be “essential” because the body cannot manufacture them from other amino acids . These have to be present in food . Ideally , dietary proteins should contain all the essential amino acids , in the ratios in which the body requires them . If any one essential amino acid is present in less than the ideal quantity , then the quality and the dietary value of the whole protein are compromised . The essential amino acid that is least well represented becomes the ‘limiting factor’ , dragging down the quality of the whole . (…)

about protein : http://diagnosisdiet.com/food/protein/

Since we can’t make proteins from scratch, and we can’t store excess protein, protein is the only macronutrient that we absolutely must eat regularly in order to thrive. Without enough protein in the diet, the body will have no choice but to break down muscle fibers to release the protein it needs to survive.

Proteins are made up of small building blocks called amino acids. While there are hundreds of amino acids, there are only 20 amino acids used to build proteins. By combining these 20 amino acids in different sequences, cells can create thousands of unique proteins. Amino acids are like letters of the alphabet, and our cells put them together in different combinations like words in a dictionary, each one with its own meaning and purpose.
There are 9 essential (or indispensable) amino acids that we cannot make from scratch under any circumstances. We must eat all 9 of these amino acids regularly:
•Histidine
•Lysine
•Threonine
•Tryptophan
•Leucine (branched)
•Isoleucine (branched)
•Valine (branched)
•Methionine (contains sulfur; can be converted to cysteine)
•Phenylalanine (can be converted to tyrosine) (…)

How did this “incomplete protein” myth become so widespread? No small misconception . The “incomplete protein” myth was inadvertently promoted in the 1971 book, Diet for a Small Planet, by Frances Moore Lappe. In it, the author stated that plant foods do not contain all the essential amino acids, so in order to be a healthy vegetarian, you needed to eat a combination of certain plant foods in order to get all of the essential amino acids. It was called the theory of “protein complementing.”

Knowing that her audience would be skeptical that a vegetarian diet could supply sufficient protein , much of the book is devoted to introducing her theory of complementing proteins, also called protein combining. This is a method of eating different plant foods together so that their combined amino acid pattern matches that of animal foods. But while Lappé was correct that combining would indeed result in a more meat-like protein profile, it is also unnecessary: Individual plant foods contain all the amino acids required by humans, in amounts which satisfy growth and maintenance; however, certain deficiencies of particular amino acids should be considered since such deficiencies can have a negative effect on health. In other words, mimicking the composition of animal proteins is not essential to human nutrition. After this was pointed out, Lappé recanted the idea of protein combining in the 10th anniversary 1981 version of the book

Unfortunately, the “incomplete protein” myth seems unwilling to die

http://engine2diet.com/question/are-plant-proteins-complete-proteins/ ( Rip ESSELSTYN )

Plants supply all the essential and nonessential amino acids. All of them. While some plants may be low in (not missing) one amino acid and other plants may be higher in another, your brilliant body sorts it all out and, at the end of the day, complements your amino-acid profile so it is perfectly balanced.

New study how much protein to eat at a meal , and how to distribute total protein intake through a day :

URL address of the link is : theglobeandmail.com/life/health-and-fitness/fitness/want-to-build-muscle-its-not-what-you-eat-but-when/article16069147/

“You can overconsume protein to your heart’s content, but unless you distribute it appropriately, you can still fall well below the body’s needs,” says Dr. Douglas Paddon-Jones, a professor of nutrition and metabolism at the University of Texas. Instead, Paddon-Jones recommends distributing protein more equally throughout the day, aiming for three meals each with 30 grams of protein – by including eggs and high-protein dairy options like Greek yogurt at breakfast, for example.

Athletes who are trying to build muscle (or simply help their muscles recover from arduous workouts) can push that approach even further. Phillips and his colleagues recently tested three different ways of taking in 80 grams of protein in one day: eight equally spaced doses of 10 grams; four doses of 20 grams; or two doses of 40 grams. The intermediate option produced the greatest overall muscle protein boost, so Phillips suggests that athletes should aim for four daily meals each with at least 20 grams of protein. And there’s one final option to boost protein synthesis at the end of the day.

If you’re a turian or a quarian, it’s definitely advisible to go with dextro-amino acids – but humans, asari, and salarians should stick with the levo-amino variety…

Found this good read on sports and nutrition :

Abstract

Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients–primarily protein and carbohydrate–in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing. Theoretically, consuming the proper ratio of nutrients during this time not only initiates the rebuilding of damaged muscle tissue and restoration of energy reserves, but it does so in a supercompensated fashion that enhances both body composition and exercise performance. Several researchers have made reference to an anabolic “window of opportunity” whereby a limited time exists after training to optimize training-related muscular adaptations. However, the importance - and even the existence - of a post-exercise ‘window’ can vary according to a number of factors. Not only is nutrient timing research open to question in terms of applicability, but recent evidence has directly challenged the classical view of the relevance of post-exercise nutritional intake with respect to anabolism. Therefore, the purpose of this paper will be twofold: 1) to review the existing literature on the effects of nutrient timing with respect to post-exercise muscular adaptations, and; 2) to draw relevant conclusions that allow practical, evidence-based nutritional recommendations to be made for maximizing the anabolic response to exercise.
