Phospholipids are well known for their role as the main component of membranes where they form the lipid bilayer due to their amphipathic character. However, phospholipids are also important as cellular messengers, enzyme activators, and more.1 Hundreds of different phospholipid molecular species are present in cells, each having variations in their phospholipid head-group or acyl tails that give them unique properties. Matreya offers an extensive list of highly purified natural and synthetic phospholipids including phosphatidylcholine, phosphatidic acid, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, phosphatidylglycerol, and phosphosphingolipids.2

Fatty Acid Composition of Matreya's Natural Lipids

Natural sphingolipids contain a heterogeneous mixture of fatty acids attached to the sphingosine moiety. The fatty acid composition is dependent on several factors including species, location within the organism, age, and environmental conditions. Normal variations in the fatty acids include chain-length, hydroxylation, and unsaturation. The percentages listed are only approximates as the actual amount will vary between lots.
