Question
Chapter 5.3, Problem 2CC
Summary Introduction
To explain: The structural feature of a polypeptide that causes a region to form transmemrane segment.
Introduction: The proteins are found in two different forms in the cell membrane. The first forms are embedded in the membrane and hence are called transmembrane proteins or integrin proteins. The other types of proteins are found at the periphery of the cell membrane and are called as peripheral proteins. These both proteins are made up of the polypeptide chains but it is the two dimensional structure that decides their role.
