Question
Chapter 3, Problem 6P
Interpretation Introduction
Interpretation:
The reason for the precipitation of proteins at high salt concentrations and some of them require salt to dissolve in water should be determined.
Concept introduction:
A peptide bond exists between the two amino acids. During the formation of a peptide bond, a molecule of water is released. The carboxyl group of one amino acid gets linked with the amino group of the other amino acid. Polypeptides and proteins are the chains formed by the amino acids.

- QUATERNARY STRUCTURE One final level of structure exists for some, but not all, proteins. This is called quaternary structure. Proteins that have quaternary structure are formed from two or more polypeptides that assemble into one active structure. The different polypeptides in a protein with quaternary structure are often called subunits. These subunits may be identical or different. One example of a protein with quaternary structure is hemoglobin, the protein that transports oxygen in our blood. The structure of hemoglobin is shown in Figure 8. B- Fe2+ Heme a Figure 8. Quaternary structure of hemoglobin with labeled subunits. Note: each subunit contains one non-protein heme group complexed to an oxidized iron atom (Fe2+). These “prosthetic groups" are required for carrying oxygen in the blood. Modified from this link under Creative Commons license.
