The glycerol portion of lipids may be derived biosynthetically by reduction of dihydroxyacetone phosphate to glycerolphosphate, and then be acylated with fatty acids or, alternatively, dihydroxyacetone phosphate may first be acylated and then reduced to 1-acyl sn glcerol-3-phosphate. Since the former pathway utilizes NADH for reduction of the C-2 carbonyl, while the latter requires NADPH, we were able to compare the relative participation of the two pathways for phospholipid synthesis by measuring the incorporation of radioactivity from tritiumlabeled NADH and NADPH into C-2 of lipid glycerol. The acyl-dihydroxyacetone phosphate pathway plays a significant role in glycerolipid synthesis in mouse liver homogenates and a clearly dominant one in Ehrlich ascites tumor cell homogenates. This finding is related to a reported lack of glycerol-3-phosphate dehydrogenase in tumor cells and to their high glycerol ether lipid content.

Our research has explored the mechanics and function of a phospholipid called acyl dihydroxyacetone phosphate (acyl DHAP). Our work has revealed that acyl DHAP plays a notable role in cell physiology and certain genetic disorders with far-reaching implications for human and animal biology. Our studies on the metabolism of acyl DHAP led to the discovery of a new lipid biosynthetic pathway, a novel biochemical reaction for the synthesis of ether bond in lipids, an unexpected subcellular site (peroxisomes) for lipid biogenesis in cells and the nature of biochemical defects in a number of genetic diseases involving peroxisomal disorders.
