[Incorporation of 1-14C-acetate into unsaponifiable lipids of slices of regenerating rat liver].

Incorporation of 14C into unsaponifiable lipids, sterols and their presursors, hydrocarbons, isolated from sections of the rat regenerating liver studied after their 6-hour incubation with 1-14C-acetate. Intensity of the label incorporation into unsaponifiable lipids and sterols increases significantly the first three days after hepatectomy and decreases on the 15th day, intensity of incorporation into hydrocarbons rises significantly the first six days and lowers on the 15th days after hepatectomy. The label is observed to be incorporated more intensively into the total unsaponifiable lipids and hydrocarbon fraction as compared to sterols, that may evidence for activation of these compounds biosynthesis at initial stages.
