The structure of cellulose?

1. Cellulose is made of a cross-ply structure, made from many macro-fibrils which are formed from

further more micro-fibrils. The latter are made from cellulose molecules which in the end are

polymers of B-Glucose.

2. B-Glucose is a ring molecule with the OH group on the Carbon-1 atom is found on the above side.

Each B-Glucose molecule is rotated at 180 degrees to other B-Glucose molecules so that OH

groups on the 1 and 4 Carbon atoms are alongside each other during the condensation process,

therefore forming Glycosidic bonds. Layers of Cellulose molecules are kept together by means of

Hydrogen Bonding, due to presence of OH groups i.e. presence of an electronegative element

Oxygen, and therefore forming micro-fibrils.

Hope it Helps :)

thanks guys(:
