[11] Caculating Charge of Polypeptide | Lehninger Chapter 3

In this video, a detailed description on how to calculate the charge of a polypeptide chain at various pH values.

The question is:

A peptide has the sequence:

Glu–His–Trp–Ser–Gly–Leu–Arg–Pro–Gly

What is the net charge of the molecule at pH 3, 8, and 11?

The polypeptide chain can be written as also EHWSGLRPG

This question is an important topic for PhD interviews and competitive exams such as #GATE, IIT JAM, #CSIR-NET, #MCAT, etc.
