With a peptide sequence QRHT what is the pI of this peptide?
 

Can someone explain the answer.I don't need just an answer; I really would like to learn how to do this.

Re: With a peptide sequence QRHT what is the pI of this peptide?
 

the PI is 10.78.

Please refere to the software "pepdraw". Search for it in google and u find it as a tulane website.

It gives you most of the information regarding your peptide.
