Function and Structure of Protein

What are the structures and functions of each kind/stage of protein?

How would a mutation or change in amino acids affect each stage?

Primary–string of amino acids to create a polypeptide chain.

(chaperonin takes in the polypeptide and releases the folded protein)

Secondary–bending and folding of peptide chain to create alpha helix or beta sheets through hydrogen bonding in the chain’s backbone.

Tertiary–3D folding due to bonds between side chains

Quaternary–combination of multiple tertiary structures

If an amino acid was deleted, added, or changed in the primary structure, the secondary, tertiary, and quaternary would all be messed up because the bonds between amino acids would be messed up. I hope that answered your question!
