Common NameDG(18:1(9Z)/18:1(9Z)/0:0)
DescriptionDG(18:1(9Z)/18:1(9Z)/0:0), also known as sn-1,2-dioleoylglycerol or sn-1,2-diolein, belongs to the class of organic compounds known as 1,2-diacylglycerols. These are diacylglycerols containing a glycerol acylated at positions 1 and 2. Thus, DG(18:1(9Z)/18:1(9Z)/0:0) is considered to be a diradylglycerol lipid molecule. DG(18:1(9Z)/18:1(9Z)/0:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. DG(18:1(9Z)/18:1(9Z)/0:0) exists in all living organisms, ranging from bacteria to humans. DG(18:1(9Z)/18:1(9Z)/0:0) participates in a number of enzymatic reactions, within cattle. In particular, CDP-Ethanolamine and DG(18:1(9Z)/18:1(9Z)/0:0) can be converted into cytidine monophosphate and PE(18:1(9Z)/18:1(9Z)) through its interaction with the enzyme choline/ethanolaminephosphotransferase. In addition, CDP-Choline and DG(18:1(9Z)/18:1(9Z)/0:0) can be converted into cytidine monophosphate and PC(18:1(9Z)/18:1(9Z)) through its interaction with the enzyme choline/ethanolaminephosphotransferase. In cattle, DG(18:1(9Z)/18:1(9Z)/0:0) is involved in the metabolic pathway called phosphatidylcholine biosynthesis PC(18:1(9Z)/18:1(9Z)) pathway.

Enzymes

General function:
Involved in ethanolaminephosphotransferase activity
Specific function:
Catalyzes phosphatidylethanolamine biosynthesis from CDP-ethanolamine. It thereby plays a central role in the formation and maintenance of vesicular membranes. Involved in the foramtion of phosphatidylethanolamine via 'Kennedy' pathway (By similarity).

General function:
Not Available
Specific function:
Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. In contrast to DGAT2 it is not essential for survival. May be involved in VLDL (very low density lipoprotein) assembly. Functions as the major acyl-CoA retinol acyltransferase (ARAT) in the skin, where it acts to maintain retinoid homeostasis and prevent retinoid toxicity leading to skin and hair disorders. In liver, plays a role in esterifying exogenous fatty acids to glycerol.
