Polysaccharides are used as a source of carrageenans, alginates, and agar. Polysaccharides are classified as insoluble and soluble fibers, based upon their solubility. The insoluble fibers, commonly known as sulfated galactans (carrageenans, agars, floridean, xylans, and starch) are obtained from the red algae (rhodophyta).

It exists only in plants, stored in the seeds, roots, and fibers as a food reserve. The chief sources of starch are cereals, potatoes, corn, and rice. The biological functions include, in plants, the main way of storage of sugar, and of energetic sources; in humans, the first supply of glucose on a diet.
