CC   -!- FUNCTION: Catalyzes the NADPH-dependent reduction of a wide variety of
CC       carbonyl-containing compounds to their corresponding alcohols. Displays
CC       enzymatic activity towards endogenous metabolites such as aromatic and
CC       aliphatic aldehydes, ketones, monosaccharides and bile acids. Acts as
CC       an aldehyde-detoxification enzyme (By similarity). Displays no
CC       reductase activity towards retinoids (By similarity).
CC       {ECO:0000250|UniProtKB:P14550, ECO:0000250|UniProtKB:P50578,
CC       ECO:0000250|UniProtKB:P51635}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a primary alcohol + NADP(+) = an aldehyde + H(+) + NADPH;

CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:Q9JII6}. Apical cell membrane
CC       {ECO:0000250|UniProtKB:Q9JII6}.
CC   -!- SIMILARITY: Belongs to the aldo/keto reductase family. {ECO:0000305}.
