Lactaldehyde is an intermediate in the methylglyoxal metabolic pathway. Methylglyoxal is converted to D-lactaldehyde by glycerol dehydrogenase (gldA). Lactaldehyde is then oxidized to lactic acid by aldehyde dehydrogenase.
== Structure == Lactaldehyde is a three-carbon atom species with a carbonyl group on the first carbon atom (making it an aldehyde), and a hydroxy group on the second carbon atom, making it a secondary alcohol. The molecule is chiral, its stereocenter being located on the second carbon atom.
