Humans cannot digest cellulose as the digestive system of humans do not have cellulase, the enzyme which digests the cellulose. Cellulose is composed of long chains of polymeric polysaccharide carbohydrate. Cellulose is the main constituent of the cell in most plants and it is used in the manufacture of plant based products such as paper, textiles and organic pharmaceuticals.
