| 1.1.1.48 | D-galactose + NAD+ = D-galactono-1,4-lactone + NADH + H+ |
B-type enzyme with regard to stereochemistry, transfers hydrogen from carbon-1 of D-galactose to si face of NAD, in the reverse reaction the pro-S hydrogen atom from carbon-4 of NAD(P)H is transferred to the re face of carbon-1 of D-galactono-1,5-lactone |

| 1.1.1.48 | D-galactose + NAD+ = D-galactono-1,4-lactone + NADH + H+ |
depending on the pH, the immediately formed D-galactono-1,5-lactone rearranges intramolecularly to the corresponding 1,4-lactone or hydrolyzes to D-galctonate or both |
