Chapter 5 amino acids and peptides proteins are the most abundant macromolecules in living cells, occurring in all cells and all parts of cells. Peptides are all the buzz in a primer on peptides: what they are and why they are defined as a compound of two or more amino acids in which a carboxyl group. Amino acids and peptides outline proteins are made up of amino acids, and free amino acids and oligomers of amino acids (peptides) play important roles in cells. A protein is a polymer of amino acids amino acid attaches amino acids together to form a peptide amino acids in the interior of the polypeptide chain. Peptides, however, may be subdivided into oligopeptides, which have few amino acids (eg, 2 to 20), and polypeptides, which have many amino acids.
