Question

what is the net charge of the following sequence VIRALPANDEMIC at ph 7?

Answer 1

but at pH 7, arginine side chain will accept one H+ and thus will have one POSITIVE charge.

And aspartic acid and glutamic acid both will emit one H+ each at pH 7 and will bear one negative charge each.

So total two negative charge

So net 3 negative charge and two positive charge.

So net charge at pH 7 will be -1.
