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...

3b: a simple tertiary structure. Be sure to save an image for your lab report. Observe: Draw a sketch of the peptide, including where you would expect to find H-bonds and the location of the hydrophobic amino acids. Reflect: How does primary sequence relate to the stability of the peptide's folded structure? In other words, how does the pattern of hydrophobic residues effect protein stability? Briefly examine you prelab model and describe any changes you might make.
