Abstract

The in vivo incorporation of 1-14C-palmitic acid and 1-0-[8,9-3H] hexadecyl glycerol (chimyl alcohol) by plasmodia of the slime mold,Physarum polycephalum has been studied.14C-palmitate rapidly enters ester and alkyl ether side chains of phospholipids, but alk-1-enyl side chains are labeled more slowly.3H-chimyl alcohol is incorporated into the alkyl ether phospholipids, which appear to undergo enzymatic desaturation, producing plasmalogens. The feasibility ofPhysarum as the source of a cell-free enzyme system for plasmalogen synthesis is discussed.
