Metabolite Identification
Common NameDG(19:0/20:0/0:0)[iso2]
DescriptionDG(19:0/20:0/0:0), also known as diacylglycerol(39:0) or DG(19:0/20:0), 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(19:0/20:0/0:0) is considered to be a diradylglycerol lipid molecule. DG(19:0/20:0/0:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. DG(19:0/20:0/0:0) participates in a number of enzymatic reactions, within cattle. In particular, DG(19:0/20:0/0:0) can be biosynthesized from PA(19:0/20:0) through the action of the enzyme phosphatidate phosphatase. Furthermore, DG(19:0/20:0/0:0) and anteisopentacosanoyl-CoA can be converted into TG(19:0/20:0/a-25:0) through the action of the enzyme diacylglycerol O-acyltransferase. Furthermore, DG(19:0/20:0/0:0) can be biosynthesized from PA(19:0/20:0); which is mediated by the enzyme phosphatidate phosphatase. Finally, DG(19:0/20:0/0:0) and isotetracosanoyl-CoA can be converted into TG(19:0/20:0/i-24:0); which is catalyzed by the enzyme diacylglycerol O-acyltransferase. In cattle, DG(19:0/20:0/0:0) is involved in a couple of metabolic pathways, which include de novo triacylglycerol biosynthesis TG(19:0/20:0/a-25:0) pathway and de novo triacylglycerol biosynthesis TG(19:0/20:0/i-24:0) pathway.
