Definition for Sucrose
From Biology Forums Dictionary
Table sugar - sucrose - is a disaccharide consisting of glucose and fructose [O-α-D-glucopyranosyl-(1→2)-β-D-fructofuranoside]. Sucrose synthesis occurs in plants by way of fructose 6-phosphate and UDP-glucose. These two are joined through an O-glycosidic link via the anomeric carbon positions of both monosaccharides in a reaction catalyzed by sucrose 6-phosphate synthase. This reaction yields sucrose 6-phosphate, and this phosphate ester is hydroyzed to form sucrose.
