I am very confused on the meaning of microfibrils/fibres and what the difference is/what they are and what they have to do with hydrogen bonding? Particularly in regards to in cellulose in the cell wall in biology. Can some please help? Thanks

Cellulose is a component of the cell wall; main role being to keep the cell turgid and give it strength. This is why whilst animal cells can shrink totally in size due to osmosis, plant cells will maintain their shape after a lot of osmosis has occurred due to the cellulose.

The cellulose component is made from a chain of beta glucose monomers which means the chain is straight as the glycosidic bonds are alternating at every glucose molecule. This means they form a straight chain, but they also form INTERMOLECULAR forces between each chains, due to the -OH groups on the glucose molecules which can form strong dipoles hence HYDROGEN bonds. So to conclude with cellulose, it is the only one from what you've mentioned that has anything to do with H-BONDS and make up the MICROFIBRILS.

FIBRES on the other hand are those that make up muscles, etc, thin strands with a thread like structure with thick walls, whereas microfibrils are very small line thin strands found mainly on plants cell walls.

Thank you for the reply. What do microfibrils actually consist of? Is it just many hydrogen bonds?
