Question

Draw a schematic of the chemical structure of the Ala-Trp-Met-Lys tetrapeptide, with the correct ionization at neutral pH (pH 7). Also, give an estimate of the pI of this tetrapeptide (you are given that the pKa of any acidic R group is 4, the pKa of any basic R group is 11.5, and the pKa of the α-COOH is 2, and the α-NH3 is 9.5). Provide rationale!
