Chemical Taxonomy
Description belongs to the class of organic compounds known as 1-alkyl,2-acylglycerophosphates. These are glycerophosphates in which the O-1 atom of the glycerol is bonded to a fatty acid (saturated or unsaturated) through an ether linkage, and the O-2 atom is bonded to another fatty acid through an ester linkage.
