Related to phosphatidic acid: Phosphatidylserine
phos·pha·tid·ic ac·id(fos'fă-tid'ik as'id),
1,2-Diacylglycerol phosphate; a derivative of glycerophosphoric acid in which the two remaining hydroxyl groups of the glycerol are esterified with fatty acids; for example, phosphatidic acids attached to choline are phosphatidylcholines (lecithins).
phosphatidic acid/phos·pha·ti·dic ac·id/ (-tid´ik) any of a group of compounds formed by esterification of three hydroxyl groups of glycerol with two fatty acid groups and one phosphoric acid group; from it are derived the phosphoglycerides.
a precursor of triacylglycerols and some phospholipids. Its biologically important derivatives include cardiolipin and compounds consisting of a phosphate ester linked to ethanolamine, inositol, serine or choline, i.e. phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine.
