Question

describe using the language of the unit, the structure of the polysaccharide,Linear Mannan

Answer 1

Polysaccharides are complex biomacromolecules which are made up of chains of monosaccharides units. The bonds that form these chains are glycosidic bonds. These glycosidic bonds consist of an oxygen molecule bridging two carbon rings. The bond is formed when a hydroxyl group is lost from the carbon of one molecule, while the hydrogen is lost by the hydroxyl group of another monosaccharide. Because two molecules of hydrogen and one of oxygen are expelled, the reaction is a dehydration reaction. The structure of the molecules being combined determines the structures and properties of the resulting polysaccharide.

Types -

Homopolysaccharides – are made up of one type of monosaccharide units. ex: cellulose, starch, glycogen.

Heteropolysaccharides – are made up of two or more types of monosaccharide units. ex. hyaluronic acid
