Glycerol 3-phosphate is synthesized by reducing dihydroxyacetone phosphate (DHAP), an intermediate in glycolysis. The reduction is catalyzed by glycerol-3-phosphate dehydrogenase. DHAP and thus glycerol 3-phosphate can also be synthesized from amino acids and citric acid cycle intermediates via the glyceroneogenesis pathway. + NAD(P)H + H + → ...
Thus, the two substrates of this enzyme are sn-glycerol 3-phosphate and D-glucose, whereas its two products are glycerol and D-glucose 6-phosphate. This enzyme belongs to the family of transferases , specifically those transferring phosphorus-containing groups ( phosphotransferases ) with an alcohol group as acceptor.
The first step is the acylation of glycerol-3-phosphate by a glycerol-3-phosphate acyltransferase. Then acylglycerol-3-phosphate can be once more acylated to form a phosphatidic acid (PA). With the help of the enzyme CDP-DAG synthase (CDS) ( phosphatidate cytidylyltransferase ), PA is converted into cytidinediphosphate -diacylglycerol (CDP-DAG).
In enzymology, a glycerol-3-phosphate dehydrogenase (NAD +) (EC 1.1.1.8) is an enzyme that catalyzes the chemical reaction. sn-glycerol 3-phosphate + NAD + glycerone phosphate + NADH + H + The two substrates of this enzyme are sn-glycerol 3-phosphate and NAD +, whereas its 3 products are glycerone phosphate, NADH, and H +.
The third carbon links to an ethanolamine or choline by means of a phosphate ester. These compounds are key components of the membranes of muscles and nerves. Phosphatidates. Phosphatidates are lipids in which the first two carbon atoms of the glycerol are fatty acid esters, and the 3 is a phosphate ester. The phosphate serves as a link to ...
Thus, the two substrates of this enzyme are sn-glycerol 3-phosphate and NADP +, whereas its 3 products are D-glyceraldehyde 3-phosphate, NADPH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-OH group of donor with NAD + or NADP + as acceptor.
In enzymology, a glycerol-3-phosphate cytidylyltransferase (EC 2.7.7.39) is an enzyme that catalyzes the chemical reaction. CTP + sn-glycerol 3-phosphate diphosphate + CDP-glycerol. Thus, the two substrates of this enzyme are CTP and sn-glycerol 3-phosphate, whereas its two products are diphosphate and CDP-glycerol.
In enzymology, a glucosylglycerol-phosphate synthase (EC 2.4.1.213) is an enzyme that catalyzes the chemical reaction ADP-glucose + sn-glycerol 3-phosphate ⇌ {\displaystyle \rightleftharpoons } 2-(beta-D-glucosyl)-sn-glycerol 3-phosphate + ADP
