Metabolite Identification
Common Name2-Amino-4-ethoxy-3-hydroxybutanoic acid
Description2-Amino-4-ethoxy-3-hydroxybutanoic acid belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2-Amino-4-ethoxy-3-hydroxybutanoic acid has been detected, but not quantified in, a few different foods, such as common mushrooms (Agaricus bisporus), mushrooms, and oyster mushrooms (Pleurotus ostreatus). This could make 2-amino-4-ethoxy-3-hydroxybutanoic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Amino-4-ethoxy-3-hydroxybutanoic acid.
