DescriptionDG(18:1(11Z)/18:1(11Z)/0:0) Belongs to the class of organic compounds known as 1,2-diacylglycerols. These are diacylglycerols containing a glycerol acylated at positions 1 and 2. DG(18:1(11Z)/18:1(11Z)/0:0) Is an extremely weak basic (essentially neutral) compound (based on its pKa). Since diacylglycerols are synthesized via phosphatidic acid, they will usually contain a saturated fatty acid at the C-1 position on the glycerol moiety and an unsaturated fatty acid at the C-2 position. CDP-ethanolamine and DG(18:1(11Z)/18:1(11Z)/0:0) Can be converted into cytidine monophosphate and PE(18:1(11Z)/18:1(11Z)); which is mediated by the enzyme choline/ethanolaminephosphotransferase. In humans, DG(18:1(11Z)/18:1(11Z)/0:0) Is involved in phosphatidylethanolamine biosynthesis. Dacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections. Glycerol-3-phosphate is first acylated with acyl-coenzyme A (acyl-CoA) to form lysophosphatidic acid, which is then acylated with another molecule of acyl-CoA to yield phosphatidic acid. DG(18:1(11Z)/18:1(11Z)/0:0) Is a diglyceride, or a diacylglycerol (DAG). Phosphatidic acid is then de-phosphorylated to form diacylglycerol. DG(18:1(11Z)/18:1(11Z)/0:0), In particular, consists of two chains of vaccenic acid at the C-1 and C-2 positions. It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Diacylglycerols are precursors to triacylglycerols (triglyceride), which are formed by the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase. Synthesis of diacylglycerol begins with glycerol-3-phosphate, which is derived primarily from dihydroxyacetone phosphate, a product of glycolysis (usually in the cytoplasm of liver or adipose tissue cells). Diacylglycerols can have many different combinations of fatty acids attached at both the C-1 and C-2 positions. The vaccenic acid moieties are derived from butter fat and animal fat.
