Sucrose is made up of
A
glucose + fructose
B
glucose + glucose
C
glucose + ribose
D
glucose + galactose
Explanation: 

Detailed explanation-1: -Sucrose is composed of one molecule of glucose and one molecule of fructose, -d-glucopyranosyl-d-fructofuranoside. It is the traditional sweetener, table sugar. It is highly water soluble and is present in most fruits, some root vegetables, many trees, and grasses.

Detailed explanation-2: -Sucrose is composed of a molecule of glucose joined to a molecule of fructose by an -1, -2-glycosidic linkage.

Detailed explanation-3: -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-4: -Monosaccharides are made of one sugar unit and are the most basic form of sugar. Example of monosaccharides – glucose and fructose. Disaccharides are formed with the dehydration reaction. They are formed with two monosaccharides by removing a water molecule.

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.
