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) = (1.18)/(2) = 5.9`
