Metabolite Identification
Common Name3-Oxohexadecanoic acid
Description3-Oxohexadecanoic acid, also known as 3-oxohexadecanoic acid, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. 3-Oxohexadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Oxohexadecanoic acid exists in all eukaryotes, ranging from yeast to humans. 3-Oxohexadecanoic acid participates in a number of enzymatic reactions, within cattle. In particular, 3-Oxohexadecanoic acid can be biosynthesized from myristic acid and malonic acid through its interaction with the enzyme fatty acid synthase. Beta ketoacyl synthase domain. In addition, 3-Oxohexadecanoic acid can be converted into (R)-3-hydroxy-hexadecanoic acid; which is mediated by the enzyme fatty acid synthase. Beta ketoacyl synthase domain. In cattle, 3-oxohexadecanoic acid is involved in the metabolic pathway called fatty acid biosynthesis pathway.
