Radioactive labelling of lipids in rat neurosarcoma by intravenous injection of [1-14C]-octadecenol.

Radioactivity from cis-9-[1-14C]octadecenol, injected intravenously into rats bearing neurosarcoma, is incorporated to a significantly greater extent into tumor than into muscle. In the lipids of both tissues, radioactivity is incorporated predominantly into the acyl moieties, rather than into the alkyl or alk-1-enyl moieties, of diradylglycerophosphocholines, diradylglycerophosphoethanolamines, and triradylglycerols.
