Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What makes up the disaccharide sucrose?
A
glucose + glucose
B
glucose + fructose
C
glucose + galactose
D
glucose + maltose
Explanation: 

Detailed explanation-1: -Disaccharides are made up of two linked monosaccharides and are broken back down into monosaccharides during digestion ( 1 ). Sucrose is a disaccharide consisting of one glucose molecule and one fructose molecule, or 50% glucose and 50% fructose.

Detailed explanation-2: -Sucrose, which is formed following photosynthesis in green plants, consists of one molecule of glucose and one of fructose bonded via an -, -linkage.

Detailed explanation-3: -Disaccharides. Disaccharides are composed of two monosaccharide units linked together by a glycosidic bond. The most common glycosidic bonds connecting monosaccharide units are O-glycosidic bonds in which the oxygen from a hydroxyl group becomes linked to the carbonyl carbon.

Detailed explanation-4: -A disaccharide (also called a double sugar ) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.
