Explanation

Polysaccharides are large sized carbohydrates $\left( C_{6}H_{10}O_{5} \right)_{n}$ which are formed by condensation of a number of monosaccharides. These are also called glycan because of their formation from sugars. Linkage between adjacent monosaccharides is through glycosidic bonds $( - COC - )$. A molecules of water is released at each point of condensation.
