Formation of ether lipids from isomeric cis-octadecen-1-ols in normal and neoplastic cells: substrate specificity of enzymes with regard to position of double bonds.
The pattern of incorporation of isomeric cis-[1-14C]octadecen-1-ols into alkyl moieties of glycerophospholipids of rat brain as well as of L 1210 and S 180 murine ascites cells revealed the following: 1) The enzymes involved in the biosynthesis of acylalkylglycerophospholamines have no substrate specificity with regard to position of the double bond of either cis-oectadecen-1-ols or of intermediate ether lipids derived therefrom. 2) CDPcholine: diradylglycerol cholinephosphotransferases exhibit a strong preference for acylalkylglycerols with cis-8, cis-9 and cis-10-octadecenyl moieties as substrates.
