Vinyl ether linkage

Apply bands of sample solution, overspray with [35] 12% hydrochlonc acid, leave in an atmosphere of nitrogen for 2 imn and then dry in a stream of nitrogen, then chromatograph The vinyl ether linkages in the phosphatides are hydrolyzed...

There are also differences in the composition of the phospholipids in human platelets. These cells contain a little over twice as much phosphatidylcholine as sphingomyelin. Another dramatic difference is noted in the ether phospholipid content in the human platelets, where there is approximately 37% vinyl ether-containing components in the ethanolamine fraction whereas there only are 10% or less in the other phosphoglyceride species. The vinyl ether linkage has not been detected in the sphingolipids of these cells.

Neutral plasmalogens are related compounds in which position 1 of L-glycerol is linked by a vinyl ether bond (the double bond is of the c s-configuration) to an alkyl moiety. They have been detected in small amounts only in a few animal tissues. Although the vinyl ether linkage is stable to basic hydrolysis conditions, it is disrupted by acid (and by mercury salts) with the formation of a long-chain aldehyde, i.e.
