lipid having bond with carbon atom of glycerol and oxygen of an alkyl chain, forming an ether bond is called ether lipids
Plasmalogens are one of the classes of ether lipid having vinyl ether bond at sn-1 position and a phospholipid at one of carbon atom of glycerol
In 1924, Feulgen and Voigt [2] coined the term plasmalogen to describe an unknown compound that produced a plasma aldehyde after acid treatment
GP species are distinguished by their polar head group at the sn-3 position of the glycerol backbone, mainly being choline or ethanolamine, and to a lesser extent, inositol, serine or rarely, threonine. Further diversity is introduced by the components at the sn-1 and sn-2 positions, composing subclasses of diacyl and ether GP.
