Chemical Information
FooDB Name2-oxobutanoate
Description3-methyl pyruvic acid, also known as alpha-ketobutyric acid or 2-oxobutyric acid, belongs to short-chain keto acids and derivatives class of compounds. Those are keto acids with an alkyl chain the contains less than 6 carbon atoms. Thus, 3-methyl pyruvic acid is considered to be a fatty acid lipid molecule. 3-methyl pyruvic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 3-methyl pyruvic acid can be found in a number of food items such as pepper (c. baccatum), triticale, european plum, and black walnut, which makes 3-methyl pyruvic acid a potential biomarker for the consumption of these food products. 3-methyl pyruvic acid can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine. 3-methyl pyruvic acid exists in all living species, ranging from bacteria to humans. In humans, 3-methyl pyruvic acid is involved in several metabolic pathways, some of which include methionine metabolism, homocysteine degradation, threonine and 2-oxobutanoate degradation, and propanoate metabolism. 3-methyl pyruvic acid is also involved in several metabolic disorders, some of which include dimethylglycine dehydrogenase deficiency, methylenetetrahydrofolate reductase deficiency (MTHFRD), s-adenosylhomocysteine (SAH) hydrolase deficiency, and hyperglycinemia, non-ketotic.
