How many sugar units (monomers) make up disaccharides?
A
one
B
two
C
three
D
zero
Explanation: 

Detailed explanation-1: -1.2 Disaccharide. Disaccharide consists of two monosaccharide units linked together by a glycosidic bond which is formed by condensation reaction between hydroxyl group of one monosaccharide with the hydrogen of another monosaccharide.

Detailed explanation-2: -Disaccharides. Disaccharides are sugars that are made up of two single sugar units joined together. Lactose, the main sugar found in milk, is a disaccharide, and it has a galactose and a glucose molecule. Table sugar, also known as sucrose, is extracted from sugar cane and is another example.

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.
