Metabolite Identification

Common Name

3-Hydroxyisoheptanoic acid

Description

3-Hydroxyisoheptanoic acid belongs to the class of organic compounds known as medium-chain hydroxy acids and derivatives. These are hydroxy acids with a 6 to 12 carbon atoms long side chain. 3-Hydroxyisoheptanoic acid has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 3-hydroxyisoheptanoic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Hydroxyisoheptanoic acid.
