Answer:
Step-by-step explanation:
Proteins are made up of amino acids. Amino acids are the simply the monomeric units of proteins. An amino acid is bifunctional in that it carries an amino group(-NHâ‚‚) and a carboxyl group(-COOH) attached to a carbon atom in a molecule.
Amino acids can form long polyamide chains that makes up proteins. A peptide bond binds an amino group of the first amino acid molecule with the carboxyl group of the second amino acid molecule.
Proteins are high polymers made up of one or more peptide chains.
