Metabolite Identification
Common NameAngelic acid
DescriptionAngelic acid is found in fats and oils. Angelic acid is a constituent of Angelica archangelica (angelica) Angelic acid has a double bond between the second and third carbons of the chain. Together with tiglic acid form a pair of cis-trans isomers. Angelic acid is a volatile body, of biting acid taste and pungent sour odour. It crystallizes in colorless monoclinic prisms. Angelic acid was formerly used therapeutically as a sedative. Angelic acid is a monocarboxylic unsaturated organic acid. It is found in garden angelica (Angelica archangelica), Umbelliferae, and many other plants. It was also isolated from the defensive secretion of certain carabid beetles

Chemical Taxonomy
Description 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.
