Monomers & Polymers
Biology: AQA A Level, topic 1.1.1
Monomers and Polymers
There is a huge variety of species on earth. Despite this incredible diversity, all living organisms are made up of similar biological molecules called monomers.
Monomers
- Monomers are the single subunits, or building blocks, of life.
- E.g. Amino acids, nucleotides and monosaccharides.
Polymers
- Polymers are complex molecules that are formed by combining monomers using covalent bonds.
- E.g. Protein, DNA, starch.
