| diacylglycerol | Glycerol substituted on the 1 and 2 hydroxyl groups with long chain fatty acyl residues. DAG is a normal intermediate in the biosynthesis of phosphatidyl phospholipids and is released from them by phospholipase C activity. DAG from phosphatidyl inositol polyphosphates is important in signal transduction. Elevated levels of DAG in membranes activate protein kinase C by stabilising its catalytically active complex with membrane bound phosphatidyl serine and calcium. (18 Nov 1997) |

| diacylglycerol cholinephosphotransferase | <enzyme> An enzyme that catalyses the synthesis of phosphatidylcholines from cdpcholine and 1,2-diacylglycerols. Chemical name: CDPcholine:1,2-diacylglycerol cholinephosphotransferase Registry number: EC 2.7.8.2 (12 Dec 1998) |
| diacylglycerol kinase | <enzyme> An enzyme of the transferase class that catalyses the phosphorylation of a diacylglycerol to form a phosphatidate, using ATP as a phosphate donor. Chemical name: ATP:1,2-diacylglycerol 3-phosphotransferase Registry number: EC 2.7.1.107 (12 Dec 1998) |
| diacylglycerol lipase | <enzyme> An enzyme of the hydrolase class that catalyses the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinaemia type I. Chemical name: Triacylglycero-protein acylhydrolase Registry number: EC 3.1.1.34 (12 Dec 1998) |
| diacylglycerol pyrophosphate phosphatase | <enzyme> Catalyses the dephosphorylation of the beta phosphate of diacylglycerol pyrophosphate (dgpp) to produce phosphatidate and p(i) Registry number: EC 3.6.1.- Synonym: dgpp phosphatase (26 Jun 1999) |
| UDP-sulfoquinovose 1,2-diacylglycerol 3-O-alpha-D-sulfoquinovosyltransferase | <enzyme> Catalyses the final step in the synthesis of nucleoside 5'-diphospho-sulfoquinovoses Registry number: EC 2.4.1.- Synonym: usd-sulfoquinovosyltransferase, sqdd protein, sqdd gene product (26 Jun 1999) |
| 1,2-diacylglycerol 3-glucosyltransferase | <enzyme> Catalyses the transfer of glucose from udp glucose to diacylglycerol (dag) to yield monoglucosyldiacylglycerol (mglcdag) and udp Registry number: EC 2.4.1.157 Synonym: udpg dag glucosyltransferase, udp-glucose 1,2-diacylglycerol 3-glucosyltransferase (26 Jun 1999) |
| 6-sulfoquinovosyl diacylglycerol | Quinovose containing an SO3H on C-6 and a doubly substituted glycerol on C-1; the sulfolipid occurring in all photosynthetic tissues. (05 Mar 2000) |
