Question 10 (10 pts) Peptides are biological oligomers formed by condensing multiple amino acids into an amide backbone. Although this amide backbone is common to all peptides, the so- called 'side-chan' groups attached to this backbone vary depending the amino acids used in the condensation reaction. Shown below are four different tetrapeptides (so-named because they are the products of the condensation of four amino acids). Based on their structures, predict the order of elution that one might expect if separating...
