Metabolite Identification
Common NameD-Lactaldehyde
DescriptionD- and L-lactaldehyde are also good substrates for aldose reductase. The aldose reductase-catalyzed reduction of methylglyoxal produces 95% acetol, 5% D-lactaldehyde. (PMID: 1537826 ). D-lactaldehyde is an intermediate in the pyruvate metabolic pathway. Pyruvaldehyde is irreversibly produced from D-lactaldehyde via the enzyme glyoxylate reductase (NADP+, Swiss-Prot: Q5T945).
