Question

Polysaccharide monomers are linked by

• A. Peptide bonds
• B. Glycosidic bonds
• C. Hydrogen bonds
• D. Phosphodiester bonds

Answer 1

The correct option is B Glycosidic bonds

Polysaccharides are monosaccharide linked by glycosidic bonds.

Starch is a polysaccharide formed by a-1,4 linkages between two glucose unit which is broken down during its digestion. It exists in two forms known as amylose and amylopectin. Amylose is a linear poly-D-glucose in which the monosaccharides are connected by alpha 1, 4 glycosidic linkages. Amylopectin has alpha 1, 4-glycosidic linkages with side chain branching of alpha 1,6 linkage.

So, the correct answer is option B.
