BERG/STRYER VI STUDY GUIDE CHAPTER 2 1. HOMEWORK: 1-4, 6, 8. 13. "Peeking" at the answers on p. C-1 is permitted and encouraged. Longer solutions are provided in the back of the COMPANION . Learn the structures, names, and both 1- and 3- letter abbreviations for the 20 amino acids used in protein synthesis. These are shown on pages 28-33. You should also know the ionizations shown in Table 2-1 on page 33, but you do not have to learn the exact pK a values for each. Since proteins are made of amino acids, and because amino acid metabolism and protein synthesis are covered later on, the amino acid structures will be useful throughout the course. You should be able to tell D from L amino acids. Biological amino acids are nearly always L. 2. Be able to draw peptides (p. 34). Remember that amide formation involves the loss of water, leaving amino acid "residues" behind. Understand that post-translational modifications can produce other amino acids (p. 57) and alter the properties of a protein. A
