- polymers of glucose
- cellulose
- cellulose is a polymer of beta glucose. when joining have beta 1,4 glycosidic bonding (the final structure makes a faint zig-zag.)
- hydrogen bonds are formed between cellulose molecules (o- ---> h+) these bonds are hard to break up because there's a strong attraction and an even stronger attraction when the cellulose molecules are on top of each other.
- hydrogen bonding between cellulose molecules makes many cross links hence microfibrils. cellulose molecule -----> microfibril -----> macrofibril -----> cellulose fibres

- glycogen
- animals store glucose as glycogen because glycogen doesn't dissolve in water so it wont affect osmosis.
- animals store glycogen in the liver and muscles. when the animals need glucose it breaks down the glycogen.
- there are more branches in glycogen than amylopectin so it breaks down glycogen quicker than amylopectin
- starch
- glucose is soluble in water and this affects osmosis however starch is insoluble in water and doesn't affect osmosis.
- there are different forms of starch- amylose (aplha1,4) and amylopectin (alpha1,4 and alpha1,6)
- amylose is a helix
- amylopectin makes branches
- there are different forms of starch- amylose (aplha1,4) and amylopectin (alpha1,4 and alpha1,6)
- glucose is soluble in water and this affects osmosis however starch is insoluble in water and doesn't affect osmosis.
- beta glucose OH on top
- alpha glucose OH on bottom
- cellulose
