If the pH of a protein is reduced to 1.5....below it's isoelectric point,which of it's group would be ionisable ?
i)COOH
ii)NH2
iii)Both of these
iv)Both would be neutral

i)COOH
ii)NH2
iii)Both of these
iv)Both would be neutral
-NH2 is in ionized state as a result.

Oppss, I though lower pH means release of H+ ions so I marked COO- ..one more question WRONG.

Ohh...sorry for that...but I haven't been always right, just putting my point of view to various questions...
And, yes, some questions might get wrong, but on a road for glory, little damage is always inflicted
In the end, we are going to have either a lesson or an experience, and both are worth having, so all the best once again!

I think reason is correct for the assertion. Kindly put your views forward.
