Primary Structure

sequence of amino acids in a polypeptide chain - Peptide Bonds

1 of 5

Secondary Structure

hydrogen bonds form, turns into an alpha helix coil or Folds into a beta pleated sheet. - Hydrogen bonds

2 of 5

Tertiary Structure

Coiled or folded more, More bonds form between other parts of the polypeptide chain, if the protein’s made from a single polypeptide chain this forms the final 3D structure - ionic & disulphide bonds, hydrophobic/hydrophilic interactions, hydrogen

3 of 5

Quaternary Structure

if the protein's made from more than one polypeptide chain this forms the final 3D structure. An example is haemoglobin. This is influenced by all the bonds mentioned in primary, secondary and tertiary structure.

Structure of Amino Acid

Contains a carboxyl group (COOH) and amino group (NH2) attached to a carbon atom (C) with a difference of a variable group (R)
