Which one of the following is a hetero-polysaccharide?
Open in App
Solution
The correct option is B Hyaluronic acid
- Heteropolysaccharide is a polysaccharide that is made up of more than one type of monomer.
- Homopolysaccharide is a polysaccharide that is made up of a single type of monomer.
- Glycogen is a homopolysaccharide of glucose linked by alpha-1,4-glycosidic bonds.
- Starch is a polysaccharide of glucose linked by alpha-1,4-glycosidic linkage.
- Both are homopolysaccharides, but glycogen has a branched structure (similar to amylopectin) while starch has both chain (amylose) and branched components (amylopectin).
- Cellulose is a polysaccharide of glucose linked by beta-1,4-glycosidic linkage.
- Hyaluronic acid is a polysaccharide made up of two types of sugar molecules, namely N-acetyl-glucosamine-6-phosphate and glucuronic acid.
Thus, the correct answer is option D.
