Secondary Accession NumbersNone
Metabolite Identification
Common NameLactaldehyde
DescriptionL-lactaldehyde is an intermediate metabolite in the pyruvate metabolism pathway. L-lactaldehyde is irreversibly produced from pyruvaldehyde via the enzyme aldehyde reductase (EC:1.1.1.21) which is then irreversibly converted to propylene glycol via aldehyde reductase (EC:1.1.1.21).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the NADPH-dependent reduction of a wide variety of carbonyl-containing compounds to their corresponding alcohols with a broad range of catalytic efficiencies.
Gene Name:
AKR1B1
Uniprot ID:
P15121
Molecular weight:
35853.125
Reactions
Lactaldehyde + NAD → Pyruvaldehyde + NADH + Hydrogen Iondetails
Propylene glycol + NADP → Lactaldehyde + NADPH + Hydrogen Iondetails
General function:
Not Available
Specific function:
Acts as all-trans-retinaldehyde reductase. Can efficiently reduce aliphatic and aromatic aldehydes, and is less active on hexoses (in vitro). May be responsible for detoxification of reactive aldehydes in the digested food before the nutrients are passed on to other organs.
