Metabolite Identification
Common NameBut-2-enoic acid
DescriptionBut-2-enoic acid, also known as but-2-enoic acid or (2E)-But-2-enoic acid, belongs to the class of organic compounds known as straight chain fatty acids. These are fatty acids with a straight aliphatic chain. But-2-enoic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. But-2-enoic acid exists in all living species, ranging from bacteria to humans. But-2-enoic acid participates in a number of enzymatic reactions, within cattle. In particular, But-2-enoic acid can be biosynthesized from 3-hydroxybutyric acid; which is catalyzed by the enzyme fatty acid synthase. dyhydrase domain. In addition, But-2-enoic acid can be converted into butyric acid through its interaction with the enzyme fatty acid synthase. enoyl reductase domain. In cattle, but-2-enoic acid is involved in the metabolic pathway called fatty acid biosynthesis pathway.
