1. Indicate whether each of the following molecules is an alpha amino acid or not and explain why. a. H,N-CH-ċ-OH b. H,N-C-CH,CH,CH, CH-OH CH3 c. CH;CH,CH-CH2-NH, d. HO-C-CH-CH,CH(CH), NH2 2. Which of the following forms of lysine would you expect to predominate at low pH, neutral pH, and high pH? но но NH,-C-C-o (CH.), NH3-C-C-OH NH3-C-C-0 (CH)4 NH,+ a. b. CH)4 NH,+ NH2 3. One of the 20 standard amino acids is unusual in that its side chain contains a ring that incorporates the amine functional group of the amino acid. What is the name of this amino acid? What is its three-letter abbreviation and one-letter code? Write the chemical structure of this amino acid at physiological pH. 4. Draw the structure of valine at pH 1.0 and at pH 12.0.
