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...

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
