The majority of the fibers are chemically considered polysaccharides, but not all polysaccharides are fibers ( starch for example is not a vegetable fiber ). The fibers are described as non-starchy polysaccharides ( 41 non-starch polysaccharides; Some constituents of the fibers are cellulose, hemicelluloses, pectins, gums and the mucilage. The fibers may also include some compounds not polysaccharides such as lignin ( are dozens of molecules of phenol polymer an organic alcohol with strong internal ties that make them impervious to enzymes digestive ) and the cutin, tannins. As the fiber has been investigating other chemical components have been incorporated to the list.
