Chemical Information

FooDB Name

2-Oxopropanal

Description

Pyruvaldehyde, also known as 2-oxopropanal or 1,2-propanedione, belongs to the class of organic compounds known as alpha ketoaldehydes. These are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. Pyruvaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Pyruvaldehyde exists in all living species, ranging from bacteria to humans. Pyruvaldehyde has been detected, but not quantified in, several different foods, such as common verbena, barley, shallots, abiyuchs, and garden tomato. This could make pyruvaldehyde a potential biomarker for the consumption of these foods.
