The primary structure of a protein is formed by the condensation of amino acids in a certain sequence. Consider the dipeptide formed by the condensation of glycine and tyrosine in Figure 8.31B. a. Draw the structure of the dipeptide that would be formed if the two amino acids condensed in the opposite sequence. b. How are the structures of the dipeptides in Figure 8.31B and your drawing related to each other? B 0 HN-C-0--OH HO H-N-C-C-OH H CHE H OH...

Imagine that you have just isolated a peptide hormone with the following primary sequence: MLSCRLQEALAALSKIVLADLGCVTGAPSDPR (Assume the protein is in solution at physiological pH, and remember to include the amino acids at each end of the chain. A charge may come from the R-group, the N-terminus, and/or the C-terminus. If a residue occurs more than once, include each one in your answer.) List the residues (individual amino acids) that contribute a positive charge: List the residues that contribute a...
