Answer:
polypeptides
Explanation:
Amino acids generally represent the building blocks of proteins. In order words, proteins are polymers of amino acids.
The amino acids in proteins are linked together by peptide bonds. <u>A peptide bond is formed between two amino acids when the amine group of one of the amino acids combines with the carboxylic group of the other with the elimination of water</u>. When the reaction involves multiple amino acids, multiple peptide or polypeptide, also known as protein is formed.
