甲基-Β-D-吡喃半乳糖苷 | methyl beta-D-galactopyranoside | 1824-94-8 | C7H14O6 | 194.185 |
1H nuclear magnetic resonance studies on D-galactopyranoses with chirally deuterated hydroxymethyl groups revealed that the preferred rotamer about the C5—C6 bond of the D-galactopyranoses was not tg but gt. Studies on the stereochemistry of dehydrogenation of D-galactose oxidase from Dactyliumdendroides with chirally pure deuterated methyl β-D-galactopyranosides showed that there were two mechanisms for the enzymatic reaction: an efficient pro-S hydrogen atom specific oxidation and a far less efficient non-specific or pro-R specific oxidation.
