Proteins are polymers made up of many monomers. The monomers in proteins are amino acids. Amino Acids contain the elements:
Carbon, Hydrogen, Nitrogen and Oxygen.
When two amino acids join together in they form a peptide bond.
This reaction is known as a condensation reaction as it produces water.
Proteins have four levels of structure:
⇒ Primary – sequence of amino acids in polymer
⇒Secondary – interaction between the R groups of the amino acids leads
⇒Tertiary – more folding of α helix or β pleated due to H/Ionic/Disulphide bonds.
⇒Quaternany – two or more polypeptides joined together.
