Dietary fiber is another kind of complex carbohydrate. Though it does not act as a source of energy for the body it provides many other positive benefits. Fiber is classified by nutritionists as either insoluble fiber or soluble fiber. This is based on whether it dissolves in water. Both insoluble and soluble fibers are incapable of being broken down by the body's digestive enzymes. For this reason, fiber adds no additional calories to your diet and it cannot be converted to glucose.
This indigestible carbohydrate is called fiber.
Fiber
Cellulose is indigestible to humans.
Some examples of things that are generally considered indigestible by humans include cellulose (a complex carbohydrate found in plant cell walls), certain types of fibers (such as insoluble fibers), and certain parts of animals that are difficult to break down (such as bones and cartilage). Additionally, some substances like plastic or metals are not meant to be ingested and are indigestible by the human digestive system.
Fiber
proteins, carbohydrates and fats, (fiber is a carbohydrate that is indigestible, typically cellulose)
Dietary Fiber such as bran
Cellulose is indigestible to humans because it acts as a hydrophyllic bulking agent to human feces. It is consist of non-starch polysaccharides. Its a soluble fiber, that's why cellulose is indigestible.
Dietary fiber, for humans, is indigestible. Any indigestible materials are excreted out of the body, and fiber is no exception.

Cellulose. My sources: I got it right on my quiz. (:
The major carbohydrate is cellulose. This is the form of carbohydrate we as humans can't digest. Starches are for us :)
None. Humans can't digest cellulose. Bacteria in the large intestine can digest some cellulose, creating gas and vitamin K.
