Metabolite Identification
Common NameIsovaleraldehyde
DescriptionIso-Valeraldehyde, also known as isoamyl aldehyde or 3-methyl-butanal, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. Iso-Valeraldehyde exists in all eukaryotes, ranging from yeast to humans. Iso-Valeraldehyde is an aldehydic, chocolate, and ethereal tasting compound. Iso-Valeraldehyde is found, on average, in the highest concentration within a few different foods, such as milk (cow), beers, and taco and in a lower concentration in kohlrabis, corns, and tortilla. Iso-Valeraldehyde has also been detected, but not quantified, in several different foods, such as muskmelons, highbush blueberries, fenugreeks, hazelnuts, and dills. This could make iso-valeraldehyde a potential biomarker for the consumption of these foods. A methylbutanal that is butanal substituted by a methyl group at position 3. Iso-Valeraldehyde, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, crohn's disease, perillyl alcohol administration for cancer treatment, and hepatic encephalopathy; iso-valeraldehyde has also been linked to the inborn metabolic disorder celiac disease.
