Fibers are Polysaccharides
Dietary fiber be fulfilling the role of the structural part of plants and therefore are in all foods from plant products such as vegetables, fruits, cereals and legumes. Most fibers are considered, chemically as polysaccharides, but not all fibers are polysaccharides (eg starch is a vegetable fiber). The fibers are described as non-starch polysaccharides (non-starch polysaccharides). Some constituents of the fibers are cellulose, Hemicellulose, Pectins, Gums and Mucilages. The fibers may also include some non-polysaccharide compounds such as lignin (are polymers of several dozen phenol alcohol molecules with strong internal organic make them impervious to digestive enzymes), the Cutin and tannins. As has been investigating the fiber incorporated other chemicals to the list.
