Essential Chemistry for IGCSE - Biological Molecules (Section 1 - No. 39)

Which of the following is a characteristic of the structure of proteins?
Proteins are made of a single, repeating monomer unit.
Proteins have a peptide bond (amide linkage) formed through hydrolysis.
The order of amino acids in a protein follows a regular pattern.
Proteins are formed by condensation polymerization of amino acids.
