AQA A Level Biology Monomers and Polymers.
Specification reference 3.1.1
Monomer - a small, single molecule, many of which can be joined together to form a polymer.
Polymer - a large molecule made up of many similar / identical monomers joined together.
Types of chemical reactions
Condensation Reaction
Joins 2 molecules together.
Eliminates a water molecule.
Forms a chemical bond.
Hydrolysis Reaction
Separates 2 molecules.
Requires addition of a water molecule.
Breaks a chemical bond.
.
Examples of monomers and polymers
A nucleotide is a monomer from which polymers called polynucleotides are made.
A monosaccharide is a monomer from which polymers called polysaccharides are made.
An amino acid is a monomer from which polymers called polypeptides are made.
