1) Draw the structure of the hexapeptide (Ala-Pro-Met-Lys-Met-Gly) showing all bonds and atoms and please label each amino acid in the sequence. 

2) Explain the relative mobilities (in detail) of of the amino acids Glycine (Rf = 0.29), valine (Rf=0.57), tryptophan (Rf=0.78), and lysine (Rf= 0.12) with respect to how it appears on a TLC plate made of silica gel (stationary phase) and in a mobile phase of butanol (solvent). Explain the polarity, solubility, and structural feature differences of these amino acids on the plate and how that affects its relative mobility and Rf value on the plate.
