• Proteins are linear polymers of Amino Acids (See Figure 5.1) • Each amino acid is a “residue” • 2 residues = dipeptide • 3 residues = tripeptide • 12-20 residues = oligopeptide • Many residues = polypeptide • Each polypeptide has an amino terminal and a carboxy terminal amino acid (though it may be chemically “blocked”) Insulin, with 51 amino acids, and a MW of 5,733 represents about the lower limit of what we would call a “protein” as compared with a “polypeptide”. Glutamine Synthetase, at… CONTINUE READING
