Description | DHAP(8:0) is the octanoyl derivative of Dihydroxyacetone phosphate. It is also known as an alkyl-DHAP. This compound is formed by octanoic acid reacting with DHAP. Alkyl-DHAPs are intermediates in the synthesis of ether phospholipids. The initial steps of ether phospholipid biosynthesis take place in peroxisomes. Alkyl-dihydroxyacetonephosphate synthase is the peroxisomal enzyme that actually introduces the ether linkage. Levels of Alkyl-DHAP have been found to be strongly reduced in human fibroblasts derived from Zellweger syndrome and rhizomelic chondrodysplasia punctata patients. Four other enzymes are known to be involved in the metabolism of acyl-DHAP and alkyl-DHAP. These include: acyl-DHAP/alkyl-DHAP oxidoreductase, DHAP acyltransferase, alkyl-DHAP phosphohydrolase, and a dinitrofluorobenzene-insensitive acyl-DHAP acylhydrolase. Dihydroxyacetone phosphate (DHAP) is a biochemical compound primarily involved in the glycolysis metabolic pathway. DHAP is also the product of the dehydrogenation of L-glycerol-3-phosphate which is part of the entry of glycerol (sourced from triglycerides) into the glycolytic pathway. Conversely, reduction of glycolysis-derived DHAP to L-glycerol-3-phosphate provides adipose cells with the activated glycerol backbone they require to synthesize new triglycerides. Both reactions are catalyzed by the enzyme glycerol 3-phosphate dehydrogenase with NAD+/NADH as cofactor. DHAP may be referred to as glycerone phosphate in older texts. |
