A chemically modified guanidino group is present in cimetidine (Tagamet), a widely prescribed drug for the control of gastric acidity and peptic ulcers. Cimetidine reduces gastric acid secretion by inhibiting the interaction of histamine with gastric H2 receptors. In the development of this drug, a cyano group was added to the substituted guanidino group to alter its basicity. Do you expect this modified guanidino group to be more basic or less basic than the guanidino group of arginine? Explain.

Which of these molecules is not a natural amino acid?
As we’ve discussed, a peptide bond is made when amino group of one amino acid combines with the carboxylic acid group of another amino acid (releasing a water molecule in the process). The C-N bond formed in this process is called a peptide bond. Peptide bonds have a few properties that might be unexpected. b) Another observation is that although the N-H of the peptide bond is able to serve as a H-bond donor the N atom of the peptide bond does not serve as an effective H-bond acceptor. Provide an explanation for this observation, using Lewis structures, VSEPR theory and/or valence bond theory as appropriate.c) It is also fairly accepted that while proteins undergo dynamic motions and conformational changes, and while R groups can freely rotate about Cα, it is generally not possible to freely rotate around a peptide bond. Please explain this observation, using a picture showing relevant orbitals on relevant atoms (your answer for part (a) might provide a useful basis for your reasoning…
