[{'content': 'Which of the following is a homopolysaccharide- \nSelect and explain. \nA. Heparin, B. Chitin, C. Hyaluronic acid, D. Chondroitin sulfate', 'role': 'user'}, {'content': "Answer: B \nExplanation: Ans. is 'b' i.e., Chitin o Polysaccharides are classified into -Homopolysaccharides (Homoglycans) This type of polysaccharide is made up of several units of same monosaccharide unit only. Examples are starch (multiple units of glucose), glycogen (multiple units of glucose), cellulose (multiple units of glucose), Inulin (multiple unit of fructose), Dextrin, Dextran (multiple units of glucose), and chitin.Heteropolysaccharides (Heteroglycans) This type of polysaccharide contains two or more different types of monosacharide units. Examples are heparin, heparan sulfate, chondroitin sulfate, dermatan sulfate, hyaluronic acid, keratan sulfate and blood group polysaccharides.", 'role': 'assistant'}]
