WebpI=1.88 +3.652=2.77. Calculate the isoelectric point of Lysine. Solution: Lysine has a basic group in its side chain. To calculate the isoelectric point of Lysine, the pKa of the similarly ionizable groups will be considered which are the ammonium group (pKa = 8.95) and the basic side chain (pKa = 10.53). pI=8.95+10.532=9.74.

WebWhy is the pK of the carboxyl group of glycine (2.35) so much lower than that of acetic acid (4.76)? Because the positively-charged amino group of glycine stabilizes the carboxylate group Glutamic acid has pK values of 2.10, 4.07, and 9.47 for its -carboxyl group, -carboxyl group, and -amino group, respectively. WebAmino acids are organic compounds containing two functional groups, i.e. amino (−NH3+) and carboxylate (−COO−) and an organic side chain. Twenty different amino acids are used to build a protein.
