L-Lactaldehyde is an intermediate metabolite in the pyruvate metabolism pathway and is irreversibly produced from pyruvaldehyde via the enzyme aldehyde reductase, which is then irreversibly converted to propylene glycol via aldehyde reductase.

Catabolism of the six-carbon compound L-fucose results in formation of dihydroxyacetone phosphate (C-1-to-C-3 fragment) and L-lactaldehyde (C-4-to-C-6 fragment) as intermediates. The fate of lactaldehyde depends on the respiratory growth conditions. Aerobically, lactaldehyde is oxidized to L-lactate by an NAD-linked dehydrogenase

L-Lactaldehyde is a branching point in the metabolic pathway of L-fucose and L-rhamnose utilization. Under aerobic conditions, L-lactaldehyde is oxidized to L-lactate by the enzyme lactaldehyde dehydrogenase, while under anaerobic conditions, L-lactaldehyde is reduced to L-1,2-propanediol by the enzyme propanediol

Fungal Pichia stipitis and bacterial Azotobacter vinelandii possess an alternative pathway of L-rhamnose metabolism, which is different from the known bacterial pathway. In a previous study (Watanabe S, Saimura M & Makino K (2008) Eukaryotic and bacterial gene clusters related
