Metabolite Identification
Common NamePhosphatidylserine
DescriptionPhosphatidylserine (PS) is a phospholipid nutrient found in fish, green leafy vegetables, soybeans and rice, and is essential for the normal functioning of neuronal cell membranes and activates Protein kinase C (PKC) which has been shown to be involved in memory function. In apoptosis, phosphatidylserine is transferred to the outer leaflet of the plasma membrane. This is part of the process by which the cell is targeted for phagocytosis. PS has been shown to slow cognitive decline in animal models. PS has been investigated in a small number of double-blind placebo trials and has been shown to increase memory performance in the elderly. Because of the potentail cognitive benefits of phosphatidylserine, the substance is sold as a dietary supplement to people who believe they can benefit from an increased intake. The dietary supplement was originally processed from bovine sources however Prion disease scares in the 1990s outlawed this process, and a soy-based alternative was adopted.

Chemical Taxonomy
DescriptionThis compound belongs to the class of organic compounds known as phosphatidylserines. These are glycerophosphoserines in which two fatty acids are bonded to the glycerol moiety through ester linkages. As is the case with diacylglycerols, phosphatidylserines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions.

General function:
Involved in cell adhesion
Specific function:
Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells. Probable receptor for HDL, located in particular region of the plasma membrane, called caveolae. Facilitates the flux of free and esterified cholesterol between the cell surface and extracellular donors and acceptors, such as HDL and to a lesser extent, apoB-containing lipoproteins and modified lipoproteins. Probably involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity. Receptor for hepatitis C virus glycoprotein E2. Binding between SCARB1 and E2 was found to be independent of the genotype of the viral isolate. Plays an important role in the uptake of HDL cholesteryl ester

General function:
Involved in metal ion binding
Specific function:
Catalyzes the hydrolysis of sphingomyelin to form ceramide and phosphocholine. Ceramide mediates numerous cellular functions, such as apoptosis and growth arrest, and is capable of regulating these 2 cellular events independently. Also hydrolyzes sphingosylphosphocholine. Regulates the cell cycle by acting as a growth suppressor in confluent cells. Probably acts as a regulator of postnatal development and participates in bone and dentin mineralization.
