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.{{cite journal|author-link1=Pien Chien Huang |author1=Huang PC|author2=Miller ON |title=The metabolism of lactaldehyde, page 205|journal=J.
