The focus of this nourishing natural chemistry is on synthetic components of dietary supplements and how they function biochemically, physiologically, metabolically, as well as their impact on disease. Wholesome Biochemical research is typically necessary after identifying the food and nutritional requirements in solid and debilitated individuals and treating symptoms with pharmacological drugs. Nutrition is approached scientifically through nutritional biochemistry. It describes how nutrients work at the cellular and molecular level to explain why they are necessary for human health in addition to covering the "what" of dietary requirements. Each case study either contributes to further research or helps to clarify the physiological mechanisms behind the numerous nutrition-related functions.
