Web18 uur geleden · Retaining glycoside hydrolases use acid/base catalysis with an enzymatic acid/base protonating the glycosidic bond oxygen to facilitate leaving-group departure alongside attack by a catalytic nucleophile to form a covalent intermediate. Generally, this acid/base protonates the oxygen laterally with respect to the sugar ring, which places the … Web29 dec. 2024 · X denotes the bonded atoms to the central atom, Boron is bonded with three hydrogens atoms. Therefore, X = 3 N represents the lone pair on the central atom, as per BH 3 Lewis structure, the Boron central atom has zero lone pair. Hence, N = 0 So, the AXN generic formula for the BH 3 molecule becomes AX3N0 or AX3.
