Common Name

Lactaldehyde

Description

Lactaldehyde, also known as 2-hydroxypropanal, belongs to the class of organic compounds known as alpha-hydroxyaldehydes. These are organic compounds containing an aldehyde substituted with a hydroxyl group on the adjacent carbon. The molecule is chiral, its stereocenter being located on the second carbon atom. Lactaldehyde exists in several forms: in open-chain form and as cyclic hemiacetal; in solution and in crystal forms; as monomer and as dimer. Lactaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Lactaldehyde exists in all living species, ranging from bacteria to humans. Within humans, lactaldehyde participates in a number of enzymatic reactions. In particular, lactaldehyde can be converted into pyruvaldehyde; which is mediated by the enzyme aldose reductase. In addition, lactaldehyde can be biosynthesized from propylene glycol; which is catalyzed by the enzyme aldose reductase. Methylglyoxal is converted to D-lactaldehyde by glycerol dehydrogenase (gldA). Lactaldehyde is then oxidized to lactic acid by aldehyde dehydrogenase. In humans, lactaldehyde is involved in the metabolic disorder called the leigh syndrome pathway. Lactaldehyde is an intermediate in the methylglyoxal metabolic pathway. 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. In crystal form, three conformers occur as hemiacetal dimers with a 1,4-dioxane ring skeleton:In equilibrium solution, negligibly small amounts of the monomer and at least one five-membered ring dimer exist.
