Enzyme inhibition is basically described as a reduction in enzyme-related processes. This book deals with practical techniques of enzymes used in drug experimentation. It will serve the function of both; providing applied drug assessment methods in research projects as well as helping reasonably qualified enzyme experts who wish to expand their researches further. The content has been set in a manner where fundamental aspects of enzyme obstructions of cytochromes have been followed by latest features of functional medicine treatment; reliability evaluation; and new enzyme applications from mechanistic point of view.
