The Pka values for 3-Ionisable groups x,...

The Pka values for 3-Ionisable groups x, y, z of glytamic acid are 4.3, 9.7, & 2.2 respectively.

The isoelectric point for the Aminoacid is

A

`7.0`

B

`3.25`

C

`4.95`

D

`5.95`

Text Solution

Verified by Experts

The correct Answer is:
B
PI for three ionsable group acidic amino acids
`PI=(1)/(2)(Pka_(1)+Pka_(3))=(1)/(2)(4.3+2.2)=3.25`
