CC   -!- FUNCTION: Catalyzes the saturation of all-trans-retinol to all-trans-
CC       13,14-dihydroretinol. Does not exhibit any activity toward all-trans-
CC       retinoic acid, nor 9-cis, 11-cis or 13-cis-retinol isomers. May play a
CC       role in the metabolism of vitamin A. Independently of retinol
CC       conversion, may regulate liver metabolism upstream of MLXIPL/ChREBP.
CC       May play a role in adipocyte differentiation.
CC       {ECO:0000250|UniProtKB:Q64FW2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=A + all-trans-13,14-dihydroretinol = AH2 + all-trans-retinol;
