Quizplus · Accepted Answer

Amylopectin is a branched polymer of glucose found in plants and contains both 1,4 and 1,6 glycosidic bonds. Amylose is a linear polymer of glucose and only contains 1,4 glycosidic bonds. Chitin is a polymer of N-acetylglucosamine and only contains 1,4 glycosidic bonds. Cellulose is a linear polymer of glucose but only contains 1,4 glycosidic bonds arranged in a different orientation than amylose.
