Document Summary
Ch 3 amino acids, peptides, and proteins until "some proteins contain chemical groups other than. Alpha c is chiral and optically active. Peptides can be distinguished by their ionization behavior. Peptides contain only one free alpha amino group and free carboxyl group. Biologically active peptides and polypeptides occur in a vast range of sizes. Peptides can occur at small and large lengths, all biologically important. Multisubunit - two or more identical polypeptides associated noncovalently. Oligomeric - at least two subunits are identical. Average molecular weight of 20 common amino acids = 138. When completely hydrolyzed, a protein will not usually have equal amounts of all the amino acids.
