Fiber is indigestible by humans because it is a branched chain,while starch is digestible by humans because it is unbranched.

Question

Quizplus · Accepted Answer

This statement is not completely accurate. Fiber is indigestible because humans cannot break down the beta-glycosidic bonds between the glucose molecules in the fiber. Starch, on the other hand, is a carbohydrate made up of glucose molecules linked together in a straight chain. While some starches may be branched, this does not determine whether they are digestible by humans. Starch can be broken down into glucose molecules by the enzymes in our digestive system.
