Abstract
1. 1. A wide range of dolichols differing in the length of hydrocarbon chain (from 11 to 32 isoprene residues) were found to be phosphorylated in the presence of CTP in rat liver microsomes. 2. 2. Fully unsaturated polyprenols of the same chain length as dolichols were poor substrates for dolichol kinase at low detergent (Nonidet P-40) concentration. At higher concentration of detergent, both dolichols and polyprenols were equally effective. 3. 3. In the transfer of mannosyl residues from GDPMan, the dolichyl phosphates generated in rat liver microsomes were all good lipid acceptors, while fully unsaturated polyprenyl phosphates were not.
