Chemical Information
FooDB NameGlyoxal
DescriptionGlyoxal, also known as 1,2-ethanedione or oxalaldehyde, is a member of the class of compounds known as short-chain aldehydes. Short-chain aldehydes are an aldehyde with a chain length containing between 2 and 5 carbon atoms. Glyoxal is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Glyoxal can be found in garden tomato (variety), ginger, and sesame, which makes glyoxal a potential biomarker for the consumption of these food products. Glyoxal is an organic compound with the chemical formula OCHCHO. It is a yellow-colored liquid that evaporates to give a green-colored gas. Glyoxal is the smallest dialdehyde (two aldehyde groups). Its structure is more complicated than typically represented because the molecule hydrates and oligomerizes. It is produced industrially as a precursor to many products .
