CC -!- FUNCTION: Polyol dehydrogenase that catalyzes the reversible NAD(+)-
CC dependent oxidation of various sugar alcohols. Is active with xylitol,
CC L-iditol and D-sorbitol (D-glucitol) as substrates, leading to the C2-
CC oxidized products D-xylulose, L-sorbose and D-fructose, respectively
CC (By similarity). Is a key enzyme in the polyol pathway that
CC interconverts glucose and fructose via sorbitol, which constitutes an
CC important alternate route for glucose metabolism. May play a role in
CC sperm motility by using sorbitol as an alternative energy source for
CC sperm motility (By similarity). {ECO:0000250|UniProtKB:P07846,
CC ECO:0000250|UniProtKB:Q00796}.

CC {ECO:0000250|UniProtKB:Q64442}. Note=Associated with mitochondria of
CC the midpiece and near the plasma membrane in the principal piece of the
CC flagellum. Also found in the epididymosome, secreted by the epididymal
CC epithelium and that transfers proteins from the epididymal fluid to the
CC sperm surface. {ECO:0000250|UniProtKB:Q64442}.
CC -!- SIMILARITY: Belongs to the zinc-containing alcohol dehydrogenase
CC family. {ECO:0000305}.
