Structure. Proteins are polymers made up of amino acid subunits bonded together by peptide bonds. This occurs by a condensation reaction.

Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are jo â¦ ined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues.roteins are made out of 20 smaller sub-units called amino acids. these acids contain four chemical elements: carbon, hydrogen, oxygen and nitrogen.
