Detailed explanation-1: -Sucrose is composed of −− D-glucose and −− D-fructose. These two monosaccharide units are held together by , -glycosidic linkage.
Detailed explanation-2: -Monosaccharides can bond together to form disaccharides, the most common of which is sucrose, or “table sugar.” Sucrose is 50% fructose and 50% glucose. Fructose and glucose have the same chemical formula (C6H12O6) but have different molecular structures, which makes fructose 1.2–1.8 times sweeter than sucrose.
Detailed explanation-3: -Fructose and glucose combine to form the disaccharide sucrose, which we know as common sugar. The structure of fructose, like all simple sugars, can be expressed as a six-carbon linear chain with hydroxyl and carbonyl groups.
