✦ Synopsis

Photomixotrophic cell suspension cultures of rape, Brassica napus, were incubated with rac-l-O-[ l "-a gC]hexadecylglycerol.

Radioactivity was incorporated predominantly into choline glycerophospholipids. Prolonged incubation led also 9 to considerable proportions of labeled ethanolamine glycerophospholipids. In addition to these ionic lipids, isomeric hexadecylacylglycerols as well as hexadecyldiacylglycerols were formed. About a third of the hexadecylglycerol supplied as substrate was cleaved within 48 h incubation. The palmitic acid formed by oxidative cleavage of the substrate was incorporated predominantly into choline glycerophospholipids, ethanolamine glycerophospholipids, and triacylglycerols. Incubation of an equimolar mixture of homologous saturated rac-l-O-* Nomenclature: Lipids are named according to the Recommendations (1976) of the IUPAC-IUB Commission on Biochemical Nomenclature, see Eur.
