Phosphatidylserine Is A Ubiquitous Phospholipid

Phosphatidylserine (PS), also known as serine phospholipid, diacylglyceryl phosphoserine, PS for short, is a kind of ubiquitous phospholipid, usually located in the inner layer of the cell membrane, and the phosphoglycerides in the phospholipid compound are the cell membrane. One of the components involved in a series of membrane functions. Especially in the human nervous system, it is one of the important components of the cell membrane of the brain, and at the same time plays an important role in regulating various functions of the brain (especially the memory and emotional stability of the brain). For example, it can affect the cell membrane. The fluidity, permeability, and can activate the metabolism and synthesis of a variety of enzymes. For example, there are phosphatidylcholine (19%), sphingomyelin (8%), phosphatidylethanolamine (16%) and phosphatidylserine (10%) on the human erythrocyte membrane. And only the latter have a net negative charge on the cell membrane, contributing to the asymmetry of the membrane. It can also activate damaged surface prothrombin. And with phosphatidylcholine, phosphatidylethanolamine can be converted into each other in vivo. Due to the differences between R1 and R2, phosphatidylserine has actually become a general term for a class of compounds.
