Abstract
An HPLC procedure for the isolation and quantitation of total and individual dolichyl esters in tissues has been developed. The purified lipid extracts are subjected to sequential reversed-phase, straight-phase, and reversed-phase HPLC, which yield complete resolution and high recovery of the individual dolichyl esters. The isoprenoid distribution in the esterified fraction was similar to that of the free alcohol fraction in liver, kidney, and spleen. All fatty acids present in the total fraction were also recovered in all the individual polyisoprenoids. Dolichyl esters thus appear to differ from other lipid esters in tissues in containing a broader range of fatty acids.
