cellulose

• describe the differences between cellulose and starch

  it is made from beta glucose, not alpha glucose

  cellulose has straight, unbranched chains that run parallel to one another- this allows hydrogen bonds to from cross-linkages between adjacent chains

  the amount of hydrogen bonds strengthens the cellulose

  cellulose is the main component of plant cell walls and provides rigidity to the plant cell

  cellulose molecules are grouped together to form microfibrils, which are grouped to form fibres
• give the function of cellulose

  cellulose is the main component of plant cell walls and provides rigidity to the plant cell

  It also prevents the cell from bursting as water enters it via osmosis- by exerting an inward pressure that stops any influx of water
• describe how cellulose is bonded

  every other glucose molecule is rotated 180 degrees, this allows hydrogen bonds to be formed between hydroxyl groups on adjacent parallel chains to help give cellulose its structural stability
