Product name: phosphatidyl serine
phosphatidyl serine source: Extracted from the soybean. The beans can be processed into soy protein, which is a powder; soymilk, which is a beverage that may or may not be fortified with extra calcium from the soybeans; or soy fiber, which contains some of the fibrous parts of the bean.
phosphatidyl serine introduction: Phosphatidylserine (PS) is from the phospholipids family, which is the only one that could control the functioning of key membrane proteins.
Usually it refers to a series of compounds of PS, in that the lipid-acetyl residues differ greatly in variety of product sources.
PS exists in all biomembranes of animals, higher plants and microbes as an important component ofcellular phospholipids, for example, it makes 10-20%of total phospholipids in brains of mammals, and plays essential roles in many cellular metabolic process.
