cellulose has hydrogen bond cross links between th straight parallel layers which increases strength for it to act as a cell wall?

Is this an exam question? If so, how many marks?

Cellulose consists of beta-glucose molecules linked with 1-4 glycosidic bonds. This forms a long chain of glucose monomers. These chains also have crosslinks between them every so often which are hydrogen bonds. This increases the strength of the polymer making it ideal for use in cell walls to keep the cell from bursting due to osmotic gains or loss. To add even further strength, the molecules are grouped to form microfibrils which in turn are grouped to form fibres.

Hope this helps...

Almost every 3rd amino acid is glycine - which has the simplest (smallest) R group. This allows the structure to be tightly wound up. Also, hydrogen bonds form between individual strands as well as bonds made between the parallel fibre's R groups. All of this strengthens the protein, giving it the tensile strength of mild steel.
