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.

Students have asked these similar questions
An understanding of the structure and function of membrane proteins has lagged behind that of other proteins. The primary reason is that membrane proteins are more difficult to purify and crystallize. Why might this be the case?
What are integral membrane proteins? Under how many types is it examined? Briefly explain
What is the likely identity of these membrane associated proteins: (a) a protein that is released from a membrane treated with a high salt solution, which causes disruption of ionic linkages; (b) a protein that is not released from the membrane upon its exposure to a high salt solution alone, but is released when the membrane is incubated with an enzyme that cleaves phosphate glycerol bonds and covalent linkages are disrupted; (c) a protein that is not released from the membrane upon exposure to a high salt solution, but is released after the addition of the detergent sodium dodecylsulfate (SDS). Will the activity of the protein released in part (c) be preserved following its release?
