Question

The skeletal structures of the two amino acids, glycine and lysine, are given below along with the values of the relevant acid dissociation constants (pKa).

(b) Calculate the pI (isoelectric point) of the dipeptide, Lys-Gly, assuming that there is negligible shift in the values of acid dissociation constants from the values of the constituent amino acids.


answer = 9.985
what's the answer to part a ??
Where's part a) question?
haven't done it yet..am struggling with it..need help...
pKa+log10(10^2)= 2.35+2= 4.35
Thank you, bonjo!
