  • Description

    Phosphatidylserine powder (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 differs greatly in variety of product sources. Phosphatidylserine exists in all biomembranes of animals, higher plants and microbes as an important component of cellular phospholipids, for example, it makes 10-20% of total phospholipids in brains of mammals, and plays essential roles in many cellular metabolic process.

    Source: Any of various leguminosae seeds of soybean, having compound leaves, three leaflets, purple or white flowers and two or four seeds in the legume.
