Solution Summary

It finds the structure of the original peptide which yielded these parts following chymotrypsin and trypsin hydrolysis.

Solution Preview

The enzyme chymotrypsin cleaves peptides on the C-terminal side of hydrophobic residues such as phenylalanine and tyrosine. Look up the structures of these in order to see that they are quite hydrophobic. They both contain the ...
