Protein chemistry is a specialized skill that involves the study of the physical and chemical properties of proteins, including their structure, function and interaction with other molecules. This field is important in the development of new drugs and treatments, as well as in understanding the underlying molecular mechanisms of disease. Protein chemists use a variety of techniques, such as chromatography, electrophoresis, and spectroscopy, to isolate, purify and analyze protein structures. They also work to design and engineer new proteins with specific functions or properties, such as increased stability or catalytic activity.
