GCSE Chemistry · key term
A naturally occurring polymer made from amino acid monomers.
Used by AQA and OCR
Specification 4.7.3.3 · Paper 2
A naturally occurring polymer made from amino acids; different amino acids can occur within the same chain.
Revise: Amino Acids and PolypeptidesAt this level, chains made by combining different amino acids are described as proteins.
Specification C6.2h · Paper 2 (Foundation), Paper 4 (Higher)
Revise: Natural PolymersThe building blocks are not the same in every natural polymer: DNA is made from nucleotides, some other natural polymers are made from sugars, and proteins are made from amino acids.

Revise: Natural polymersProteins are polymers made from amino acids. Different amino acids can join in a chain to make a protein. Starch and cellulose are carbohydrates made from joined sugar units; glucose is the sugar monomer in both.
Name the monomer as well as the polymer: DNA is made from nucleotides, starch from glucose, and proteins from amino acids.
Match each natural polymer to its monomers: DNA → nucleotides; proteins → amino acids; starch and cellulose → sugars.
