DescriptionDG(22:0/22:0/0:0), also known as DG(22:0/22:0) or dg(22:0/22:0/0:0), belongs to the class of organic compounds known as 1,2-dg(22:0/22:0/0:0)s. These are dg(22:0/22:0/0:0)s containing a glycerol acylated at positions 1 and 2. Thus, DG(22:0/22:0/0:0) is considered to be a diradylglycerol lipid molecule. DG(22:0/22:0/0:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. DG(22:0/22:0/0:0) participates in a number of enzymatic reactions, within cattle. In particular, DG(22:0/22:0/0:0) can be biosynthesized from PA(22:0/22:0); which is mediated by the enzyme phosphatidate phosphatase. In addition, DG(22:0/22:0/0:0) and docosanoyl-CoA can be converted into TG(22:0/22:0/22:0) through the action of the enzyme dg(22:0/22:0/0:0) O-acyltransferase. In cattle, DG(22:0/22:0/0:0) is involved in the metabolic pathway called de novo triacylglycerol biosynthesis TG(22:0/22:0/22:0) pathway.

Reactions
CDP-Ethanolamine + DG(22:0/22:0/0:0) → Cytidine monophosphate + PE(22:0/22:0)details
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.
