Acyl dihydroxyacetone phosphate: precursor of alkyl ethers.
1-0-Alkyl dihydroxyacetone phosphate is biosynthesised in guinea pig liver mitochondria and in rat brain microsomes by direct reaction of a long chain alcohol and acyl dihydroxyacetone phosphate. ATP and Mg* are stimulatory but coenzyme A is not necessary for the reaction. 1-0-Alkyl dihydroxyacetone phosphate (alkyl DHAP)l was shown to be biosynthesized from long chain alcohol and DHAP with ATP...
متن کاملGlycerolipid biosynthesis in peroxisomes via the acyl dihydroxyacetone phosphate pathway.
In recent years, acyl dihydroxyacetone phosphate [acyl-DHAPt) has been shown to be a precursor of glycerolipids and glycerol-ether lipids.'.' Acyl-DHAP was discovered as a rapidly labeled lipid that was formed in crude mitochondrial fraction from 3'Pi or y-32P[ATP].3 This rapid labeling was due to the enzymatic dephosphorylation and rephosphorylation of endogenous acyl-DHAP present in the crude...
متن کاملThe enzymatic exchange of the acyl group of acyl dihydroxyacetone phosphate with free fatty acids.
Acyl dihydroxyacetone phosphate (acyl DHAPl) has been shown to be a precursor of glycerolipids in a variety of systems (1,2). Acyl DHAP has also been found to be the precursor of glycerol ether lipids (1,Z). It has been shown that acyl DHAP reacts with long chain alcohols to form l-O-alkyl dihydroxyacetone-3-phosphate (alkyl DHAPl) (3,4). During the investigation of the formation of the ether b...
متن کاملThe subcellular distribution of acyl CoA: dihydroxyacetone phosphate acyl transferase in guinea pig liver.
Summarv: Upon differential centrifugation, the enzyme acyl CoA:dihydroxyacetone phosphate acyl transferase (EC 2.3.1.42) in guinea pig liver is shown to sediment in a lysosomal-peroxisomal fraction. Comparison of the distribution of the marker enzymes and of DHAP acyl transferase indicates that the acyl transferase is localized in peroxisomes (microbodies). Acyl dihydroxyacetone phosphate (acyl...
متن کاملThe acyl dihydroxyacetone phosphate pathway for glycerolipid biosynthesis in mouse liver and Ehrlich ascites tumor cells.
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 we...
