What are polymers?
Large molecules consisting of many subunits called monomers
Monomers are identical or have similar subunits of a polymer
Explain polymerisation and condensation synthesis?
Process of linking monomers to form a polymer
Loss of a water molecule between two monomers to form a covalent between the monomers is ??
A condensation reaction
What is hydrolysis?
Breaking of a covalent bond between monomers by adding a water molecule
How can you tell if a chemical equation represents condensation synthesis ??
Water is a product
How can you tell if a chemical equation represents Hydrolysis?
Water is a reactant

What are the characteristics of a Cellulose polysaccharide ?
They are linear and unbranched
Is a component of plant cell walls
What are the characteristics of a Chitin polysaccharide ??
Form the exoskeleton in Arthropods, building material of cell walls in some fungi
What are the characteristics of a Glycongen polysaccharide ?
It is branched
Why can’t the human digestive system break down cellulose?
Unable to digest the type of bond where the up down position of the glycosidic bond alternates
What 4 things could make a protein complementary to a ligand?
- physical shape
- what charges it has
- what size it is
- if it’s hydrophobic or hydrophilic
