Common Name | A,b-Dihydroxyisobutyric acid |
---|
Description | A,b-Dihydroxyisobutyric acid, also known as 2,3-dihydroxy-2-methylpropionate or alpha,beta-dihydroxyisobutyrate, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. A,b-Dihydroxyisobutyric 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 a,b-dihydroxyisobutyric acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on A,b-Dihydroxyisobutyric acid. |
