2. (4 pts, 10min ) A Venn diagram that organizes the amino acids by the properties of their sidechains is shown on the right. Glycine is omitted since its sidechain is just a hydrogen atom. As the diagram suggests, a sidechain can be non-polar, charged (in the pH range 0 to 10), or polar. Some amino acids belong to more than one set, e.g. all charged residues are also polar. Venn diaeram groupine of Amino Acids based on Sidechain Properties. i) Explain Tryptophan's location on the Venn diagram (2 pts). ii) Where would you put Methionine on this diagram, justify your answer ( 2 pts)
