(a) Unbranched chain of glucose molecules linked by α 1, 4-glycosidic bond

(b) Branched chain of glucose molecules linked by β 1, 4-glycosidic bond in straight chain and α, 1, 6-glycosidic bond at the site of branching

(c) Unbranched chain of glucose molecules linked by β 1, 4-glycosidic bond

(d) Branched chain of glucose molecules linked by α 1, 6-glycosidic bond at the site of branching
