Metabolite Identification
Common Name(±)-2-Methylbutanal
Description(±)-2-Methylbutanal, also known as 2-methylbutyraldehyde, belongs to the class of organic compounds known as short-chain aldehydes. These are an aldehyde with a chain length containing between 2 and 5 carbon atoms (±)-2-Methylbutanal is an extremely weak basic (essentially neutral) compound (based on its pKa) (±)-2-Methylbutanal exists in all eukaryotes, ranging from yeast to humans (±)-2-Methylbutanal is an almond, cocoa, and coffee tasting compound. Outside of the human body, (±)-2-Methylbutanal is found, on average, in the highest concentration within kohlrabis and milk (cow) (±)-2-Methylbutanal has also been detected, but not quantified in, several different foods, such as sugar apples, horned melons, hyacinth beans, persian limes, and root vegetables. This could make (±)-2-methylbutanal a potential biomarker for the consumption of these foods. A methylbutanal in which the methyl substituent is at position 2 (±)-2-Methylbutanal, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis and nonalcoholic fatty liver disease; (±)-2-methylbutanal has also been linked to the inborn metabolic disorder celiac disease.
