Question
Chapter 23.7, Problem 23.17KCP
Interpretation Introduction
Interpretation:
The integral membrane proteins are not water soluble and the difference between the proteins from globular proteins has to be identified.
Concept Introduction:
Membrane proteins:
The membrane proteins are the proteins that interact with biological membrane and their parts of the membrane. The common types of membrane are soluble globular proteins, fibrous proteins and disordered proteins.
