Detailed explanation-1: -When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.

Detailed explanation-2: -To form polypeptides and proteins, amino acids are joined together by peptide bonds, in which the amino or NH2 of one amino acid bonds to the carboxyl (acid) or COOH group of another amino acid.

Detailed explanation-3: -Amino acids are linked together into linear chains called polypeptides. While the terms polypeptide and protein are sometimes used interchangeably, a polypeptide is technically a polymer of amino acids, whereas the term protein is a polypeptide or polypeptides that have a distinct shape and a unique function.
