Metabolite Identification
Common NameMethoxymalic acid
DescriptionMethoxymalic acid, also known as methoxymalate, belongs to dicarboxylic acids and derivatives class of compounds. Those are organic compounds containing exactly two carboxylic acid groups. Methoxymalic acid is soluble (in water) and an extremely strong acidic compound (based on its pKa). Methoxymalic acid can be found in oat, which makes methoxymalic acid a potential biomarker for the consumption of this food product.
