Question

Which of the following is/are heteropolysaccharide(s)?

• A. Chondroitin-4-sulfate
• B. Chitin
• C. Cellulose
• D. Heparin

Hint:

Heteropolysaccharides are composed of different types of monosaccharides, while homopolysaccharides are made up of one type of monosaccharide unit. Examples of heteropolysaccharides include heparin and chondroitin sulfate.

Answer 1

The Correct Option is A, D

Heteropolysaccharides are polysaccharides made up of different types of monosaccharide units. Let's analyze the options:
- (A): Chondroitin-4-sulfate is a heteropolysaccharide composed of alternating sugar units, including glucuronic acid and N-acetylgalactosamine, with sulfate groups attached. Hence, statement (A) is correct.
- (B): Chitin is a homopolysaccharide composed of N-acetylglucosamine, a single type of monosaccharide. Therefore, statement (B) is incorrect.
- (C): Cellulose is also a homopolysaccharide, made up of repeating units of glucose. Hence, statement (C) is incorrect.
- (D): Heparin is a highly sulfated heteropolysaccharide composed of disaccharide units with varying sulfation patterns. Hence, statement (D) is correct.
Thus, the correct answers are (A) and (D).
