Metabolite Identification
Common Name3-Methylbut-3-enoic acid
DescriptionIsopropenylacetic 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 only one or more methyl group. However, branches other than methyl may be present. Isopropenylacetic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
