Question: how are amylose and amylopectin similar?
Answer: Amylose consists of a linear, helical chains of roughly 500 to 20,000 alpha-D-glucose monomers linked together through alpha (1-4) glycosidic bonds. Amylopectin molecules are huge, branched polymers of glucose, each containing between one and two million residues. In contract to amylose, amylopectin is branched.
