Major lipid classes of the preputial gland of the mouse have been identified as wax ester, neutral plasmalogen, glyceryl ether diester and triglyceride. The chain lengths and degree of unsaturation in the aliphatic moieties of the alk‐1‐enyl and alkyl glyceryl ethers are similar to those of the fatty alcohols of the wax ester fraction. This lends support to the theory that long chain fatty alcohols can be direct precursors of the aliphatic chains of glyceryl ethers. The striking qualitative, as well as quantitative, similarities between the alkyl and alk‐1‐enyl moieties of the glyceryl ethers in the neutral lipid fraction suggest that they share a common pathway of biosynthesis or are interconvertible. Neutral plasmalogens and glyceryl ether diesters contain significant amounts of odd‐numbered and branched fatty acids, unlike the fatty acids of the triglycerides; therefore, the biosynthesis of neutral plasmalogens and glyceryl ether diesters may not be related to the biosynthesis of triglycerides.
