A Disaccharides is defined as a molecule formed from a combination of two monosaccharaides.
A polysaccharide is a polymer consisting of 10 or more monosaccharaides joined together . The bonds formed between the monosaccharide units are known as glycosidic bonds.
Both polysaccharides and disaccharides are sugars and can be cleaved to monosaccharide's through hydrolysis and phosphorolysis .
Both polysacahrides and disaccharides are formed by combining their constituent sugars through a reaction known as a condensation reaction which results in formation of a glycosidic bond.
