All of the following are true about cellulose EXCEPT: (select all that apply, must have all correct for credit)

a) it contains a microfibril structure due to hydrogen bonding between sugar residues in adjacent cellulose chains

b) It consists of many glucose units connected by beta (1-6) linkages

c) It is the main component of plant cell walls

d) It is well fermented by colonic bacteria

I think it is just B and D but not sure about the others.

Answer #1

Answer:

a) it contains a microfibril structure due to hydrogen bonding between sugar residues in adjacent cellulose chains

Explanation:

The strength of the cell wall is derived from layers of cellulose microfibrils that are extensively cross-linked by hemicellulose polysaccharide chains. Each microfibril consists of a bundle of linear polymers of glucose residues linked together by β(1→4) glycosidic bonds into a straight glucan chain.
