The $$p{K_a}$$ values for the three ionizable groups $$X,$$ $$Y$$ and $$Z$$ of glutamic acid are 4.3, 9.7 and 2.2 respectively
The isoelectric point for the amino acid is :
A.
7.00
B.
3.25
C.
4.95
D.
5.95
Answer :
3.25
Solution :
In acidic medium $$\frac{{4.3 + 2.2}}{2} = 3.25$$
In acidic medium $$\frac{{4.3 + 2.2}}{2} = 3.25$$
