Detailed explanation-1: -The most common disaccharide is sucrose (table sugar), which is made of glucose and fructose.
Detailed explanation-2: -Sucrose is composed of one molecule of glucose and one molecule of fructose, -d-glucopyranosyl-d-fructofuranoside.
Detailed explanation-3: -Sucrose is a disaccharide, or two-part molecule, formed by linking the monosaccharide sugars glucose and fructose.
Detailed explanation-4: -The major dietary source of galactose is lactose, a disaccharide formed from one molecule of glucose plus one of galactose. Lactose is found only in milk; after weaning, significant quantities of dietary lactose are found only in dairy products (Table 1).
Detailed explanation-5: -Sucrose is a disaccharide made up of 50% glucose and 50% fructose. It is composed of −− D-glucose and −− D-fructose. These units are held together by , -glycosidic linkage between e, of the unit and ce of the fructose unit.
