show me the mechanism of cleavageof pro-pro-leu using edmon degradation
please explain your answer
this was all the information given to me

Draw the structure of the phenylthiohydantoin product you would obtain by Edman degradation of these peptides. Show the configuration of the chirality center on the heterocycle. a) H-Ile-Leu-Pro-Phe-OH b) H-Asn-Thr-Ser-Gly-Ala-OH Please answer both A and B
Melanocyte-inhibiting factor is a tripeptide derivative, also
known as Pro-Leu-Gly-NH2. It has antidepressant and
anti-Parkinsonian effects. Design the synthesis of this compound
from amino acids Pro, Leu, and Gly. (Hint: protection and
deprotection are needed for the precise synthesis).

can
you guys help me show the reaction mechanism? using curved arrows
to indicate electron flow. thank you !
) Show the reaction mechanism clearly for the following conversion. Use curved rrows to indicate the direction of electron flow. HOOH/ heat + HBr Br
