Metabolite Identification
Common NameEicosapentaenoic acid
DescriptionEicosapentaenoic acid, also known as icosapent or cis-5,8,11,14,17-epa, 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. Eicosapentaenoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Eicosapentaenoic acid participates in a number of enzymatic reactions, within cattle. In particular, Eicosapentaenoic acid can be biosynthesized from cis-8,11,14,17-eicosatetraenoic acid; which is mediated by the enzyme fatty acid desaturase 1. In addition, Eicosapentaenoic acid can be converted into docosapentaenoic acid (22N-3); which is mediated by the enzyme elongation OF very long chain fatty acids protein 5. In cattle, eicosapentaenoic acid is involved in the metabolic pathway called the Alpha linolenic Acid and linoleic Acid metabolism pathway. Eicosapentaenoic acid has been found to be associated with several diseases known as colorectal cancer, essential hypertension, hypertension, and major depressive disorder; also eicosapentaenoic acid has been linked to the inborn metabolic disorders including isovaleric acidemia.

Enzymes

General function:
Not Available
Specific function:
Catalyzes the first and rate-limiting reaction of the four reactions that constitute the long-chain fatty acids elongation cycle. This endoplasmic reticulum-bound enzymatic process allows the addition of 2 carbons to the chain of long- and very long-chain fatty acids (VLCFAs) per cycle. Condensing enzyme that acts specifically toward polyunsaturated acyl-CoA with the higher activity toward C18:3(n-6) acyl-CoA. May participate in the production of monounsaturated and of polyunsaturated VLCFAs of different chain lengths that are involved in multiple biological processes as precursors of membrane lipids and lipid mediators (By similarity). In conditions where the essential linoleic and alpha linoleic fatty acids are lacking it is also involved in the synthesis of Mead acid from oleic acid (By similarity).
