Metabolite Identification
Common NameDG(20:3(8Z,11Z,14Z)/24:1(15Z)/0:0)
DescriptionDG(20:3(8Z,11Z,14Z)/24:1(15Z)/0:0), also known as DAG(20:3/24:1) or dg(20:3(8z,11z,14z)/24:1(15z)/0:0), belongs to the class of organic compounds known as 1,2-dg(20:3(8z,11z,14z)/24:1(15z)/0:0)s. These are dg(20:3(8z,11z,14z)/24:1(15z)/0:0)s containing a glycerol acylated at positions 1 and 2. DG(20:3(8Z,11Z,14Z)/24:1(15Z)/0:0) is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). CDP-Ethanolamine and DG(20:3(8Z,11Z,14Z)/24:1(15Z)/0:0) can be converted into cytidine monophosphate and PE(20:3(8Z,11Z,14Z)/24:1(15Z)); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. In cattle, DG(20:3(8Z,11Z,14Z)/24:1(15Z)/0:0) is involved in the metabolic pathway called phosphatidylethanolamine biosynthesis pe(20:3(8Z,11Z,14Z)/24:1(15Z)) pathway.
