Description | DG(20:1(11Z)/18:3(6Z,9Z,12Z)/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. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) Is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) Participates in a number of enzymatic reactions. In particular, DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) Can be biosynthesized from PA(20:1(11Z)/18:3(6Z,9Z,12Z)); which is catalyzed by the enzyme phosphatidate phosphatase. In addition, DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) And meadoyl-CoA can be converted into TG(20:1(11Z)/18:3(6Z,9Z,12Z)/20:3(5Z,8Z,11Z)); which is mediated by the enzyme diacylglycerol O-acyltransferase. 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. DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0), In particular, consists of one chain of eicosenoic acid at the C-1 position and one chain of g-linolenic acid at the C-2 position. Diacylglycerols can have many different combinations of fatty acids attached at both the C-1 and C-2 positions. 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). In humans, DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) Is involved in the metabolic disorder called de novo triacylglycerol biosynthesis pathway. Phosphatidic acid is then de-phosphorylated to form diacylglycerol. 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. It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. 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. DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) Is a diglyceride, or a diacylglycerol (DAG). The eicosenoic acid moiety is derived from vegetable oils and cod oils, while the g-linolenic acid moiety is derived from animal fats. Dacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections. |
