<prompt> Cellulose is not broken due to beta anomerism at:C1C2C5C6  <response>: Anomerism Different -H and -OH orientation around the functional carbon. C1 is the functional carbon in glucose. Two types of Anomers are - Alpha a - at functional carbon, -OH is downwards Beta b- at functional carbon, -OH is upwards b-anomers cant be broken in body. Cellulose is made up of glucose joined by b 1-,4 glycosidic bond In glucose functional carbon is at C1 Aldehyde. So, Cellulose is not broken due to b-anomerism at C1
