Abstract
Isolated rat liver parenchymal cells were incubated for various periods with [U-14C,2-3H]glycerol and the radioisotopic yields in the major products were determined, as well as the 3H/14C ratios in glyceride glycerol and intracellular glycerol phosphate. Under the conditions used (0.1mm-glycerol+10mm-l-lactate or 10mm-glycerol as substrates), only small differences were found between these 3H/14C ratios. The results suggest a minor role for a pathway of glyceride glycerol synthesis involving reduction of acylated dihydroxyacetone phosphate, under these experimental conditions.
