All of the statements about the peptide val-asp-trp-asn-ser are correct EXCEPT:
A) This peptide would show a strong absorption band at 280 nm.
B) Reaction with chymotrypsin would yield two peptides.
C) To synthesize this peptide using the solid phase method of Merrifield, the amino acid directly attached to the resin would be valine.
D) After the second round of Edman degradation using the reagent PITC, the PTH-amino acid residue released would be PTH-asp.
E) The peptide would be converted to a dipeptide and a tripeptide by chymotrypsin.

Question

Quizplus · Accepted Answer

In the solid-phase synthesis method, the C-terminal amino acid is attached to the resin first. In this peptide, serine is the C-terminal amino acid, not valine.
