Common Name | Isopropylmaleic acid |

Description | 2-Isopropylmaleic acid belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually they are saturated and contain one or more methyl groups. However, branches other than methyl groups may be present. 2-Isopropylmaleic acid is a moderately acidic compound (based on its pKa). Isopropylmaleic acid is found in the leucine biosynthesis pathway. It is synthesized from oxoisovalerate by 2-isopropylmalate synthase and converted into isopropyl-3-oxosuccinate by 3-isopropylmalate dehydrogenase. The 2- and 3-isopropyl derivatives of isopropylmaleic acid are interconverted by the enzyme isopropylmalate dehydratase. |
