Chemical Information
FooDB Name2-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 exists in all eukaryotes, ranging from yeast to plants to humans (±)-2-Methylbutanal is an almond, cocoa, and coffee tasting compound (±)-2-Methylbutanal is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes) and milk (cow) (±)-2-Methylbutanal has also been detected, but not quantified in, several different foods, such as dandelions (Taraxacum officinale), pepper (c. frutescens), yams (Dioscorea), eggplants (Solanum melongena), and breadfruits (Artocarpus altilis). This could make (±)-2-methylbutanal a potential biomarker for the consumption of these foods (±)-2-Methylbutanal, with regard to humans, has been found to be associated with several diseases such as nonalcoholic fatty liver disease and ulcerative colitis; (±)-2-methylbutanal has also been linked to the inborn metabolic disorder celiac disease. Based on a literature review a significant number of articles have been published on (±)-2-Methylbutanal.
