(a) Draw three different amino acid residues connected by two peptide bonds. (b) label each residue (3-letter code is OK). (c) Note bonds that do not rotate with a star (d) Note bonds that do rotate with a semi-circle arrow, including those found in each side chain (e) Of the residues in your drawing, which one contributes most to the entropy of the polypeptide (assume an unfolded state)?

Biochemistry 1: Two amino acids have chiral carbons in their side chains (R group). Identify these amino acids and draw the structures of all of the possible stereoisomers of these amino acids. The amino acid with a hydroxyl group is found in proteins with the (2S, 3R) configuration and the other amino acid is found in proteins with the (2S, 3S) configuration. Circle the structures in your answer above that correspond to these isomers.

On paper draw a dipeptide, clearly showing the peptide bond joining the two amino acids together. If the two amino acids are valine and threonine, predict the overall charge of the dipeptide at pH 7. Do not forget to consider the amino (N-terminal) and carboxy (C-terminal) of the dipeptide, as well as the R groups. Select one: a. +2 b. -2 c. 0 d. -1 e. +1
