Find iso-electric point of given amino acid
`CH_(3)-underset(o+)underset(NH_(3))underset(|)(CH)-CO_(2)H " " pK_(a) = 2.2`

A

3.3

B

5.9

C

9.6

D

11.8

Text Solution

Verified by Experts

The correct Answer is:
B
`I.P. = ( pK_(a_1) + pK_(a_2))/( 2) " so " ( (14.0 - 4.4.) + 2.2 )/( 2)= (11.8)/(2) = 5.9`
