Homopolysaccharide

Homopolysaccharides are polysaccharides composed of a single type of sugar monomer. For example, cellulose is an unbranched homopolysaccharide made up of glucose monomers connected via beta-glycosidic linkages; glycogen is a branched form, where the glucose monomers are joined by alpha-glycosidic linkages. Depending upon the molecules attached that are of the following types:
 * 1) Glucan - A polysaccharide of glucose
 * 2) Fructan - A polysaccharide of fructose
 * 3) Galactan - A polysaccharide of galactose
 * 4) Araban - A polysaccharide of arabinose
 * 5) Xylan - A polysaccharide of xylose
