Elementary Medical Biochemistry deals with the biochemical basis of the process of life, particularly, the principles of metabolic processes and the systems controlling these processes. The book reviews matter, energy, and the molecular transport processes in the body (known as diffusion, osmosis, filtration, active transport, circulation). The text also describes the medical uses of oxygen, and its functions together with hydrogen, carbon, and nitrogen. The book explains the importance of minerals in the body such as sodium, potassium, calcium, magnesium, iron, chlorine, phosphorus, sulfur, the trace elements (copper, manganese, cobalt), and other elements (nickel, cadmium, vanadium). Chemical reactions either form or break chemical bonds resulting in an uptake or release of energy. The book explains the various factors affecting the rate at which a chemical reaction occurs. These factors include temperature, concentration of reagents, or enzymes. The text also describes the metabolic fate of pyruvic acid, the glycolysis in muscle tissue, and the handling of end-products of metabolism by the body. The book is intended for students of nursing with diploma courses in general obstetrics and psychiatric nursing.
