Name: Octadecanoyl-phosphate (n-C18:1)
Description:Caprylic acid belongs to the class of Straight Chain Fatty Acids. These are fatty acids with a straight aliphatic chain. (inferred from compound structure)Caprylic acid is invovled in Biosynthesis of alkaloids derived from terpenoid and polyketide, Biosynthesis of plant secondary metabolites, and Fatty acid biosynthesis. (KEGG)Caprylic acid is the common name for the eight-carbon saturated fatty acid known by the systematic name octanoic acid. It is found naturally in the milk of various mammals, and it is a minor constituent of coconut oil and palm kernel oil. It is an oily liquid that is minimally soluble in water with a slightly unpleasant rancid-like smell and taste. Two other acids are named after goats: caproic (C6) and capric (C10). Along with caprylic acid these total 15% in goat milk fat. (WikiPedia)
