Common NamePS(18:0/20:3(8Z,11Z,14Z))
DescriptionPS(18:0/20:3(8Z,11Z,14Z)), also known as ps(18:0/20:3(8z,11z,14z)) or PS(18:0/20:3), 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. Thus, PS(18:0/20:3(8Z,11Z,14Z)) is considered to be a glycerophosphoserine lipid molecule. PS(18:0/20:3(8Z,11Z,14Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PS(18:0/20:3(8Z,11Z,14Z)) participates in a number of enzymatic reactions, within cattle. In particular, Choline and PS(18:0/20:3(8Z,11Z,14Z)) can be biosynthesized from PC(18:0/20:3(8Z,11Z,14Z)) and L-serine; which is mediated by the enzyme phosphatidylserine synthase. Furthermore, PS(18:0/20:3(8Z,11Z,14Z)) can be converted into PE(18:0/20:3(8Z,11Z,14Z)); which is catalyzed by the enzyme phosphatidylserine decarboxylase. Finally, PS(18:0/20:3(8Z,11Z,14Z)) can be converted into PE(18:0/20:3(8Z,11Z,14Z)) through its interaction with the enzyme phosphatidylserine decarboxylase. In cattle, PS(18:0/20:3(8Z,11Z,14Z)) is involved in a couple of metabolic pathways, which include phosphatidylethanolamine biosynthesis pe(18:0/20:3(8Z,11Z,14Z)) pathway and phosphatidylcholine biosynthesis PC(18:0/20:3(8Z,11Z,14Z)) pathway.
