So, I’ve been trying to sort out Sunflower lecithin powder as an ingredient, but it hasn’t been easy getting more detailed information than is listed on the nutritional label. I’ve finally managed to get an answer from a manufacturer though, when asking about the choline, omega-3 and omega-6 content. I’m just not quite sure yet what it means…
It looks like my 15g serving of sunflower lecithin powder has:
2520 mg Phosphatidylcholine
1720 mg Phosphatidylinositol
940 mg Phosphatidylethanolamine
I’m beginning to gather that to determine the choline content from this, I’m going to have to find the chemical formula for phosphatidylcholine, determine the percentage of the mol weight of the choline portion and use it to determine the gram weight. It’s been a while since I’ve taken a chemistry course, but I can probably manage that (though I wouldn’t turn down anyone offering to just tell me the answer now.)
Can someone shed some light for me on the omega-6 and omega-3 content though? I gather the manufacturer expected that the other two lines would give me that information, but I don’t see either compound in my list of omega-3 or omega-6 fatty acids. Turns out that’s because they are phospholipids. I’m not clear on the relationship between phospholipids and fatty acids. It looks like phospholipids break down into fatty acids, but I’m not clear on what I’m supposed to do to determine the omegas from this information. Any help here?
