Question
Chapter 5, Problem 2E
Summary Introduction
To explain: The ways to link the two polypeptide chains of protein through the disulfide bonds that was denatured by mercaptoethanol.
Concept introduction: Disulfide bonds play a vital role in folding and maintaining the stability of proteins. To explore the protein structure, it is important to break the disulfide bond. Mercaptoethanol is the chemical compound mainly used to reduce the disulfide bonds in proteins and to protect the sulfhydryl groups from oxidation. There are two side chains in the mercaptoethanol with the molecular weight of 40kD and 60kD, respectively.
