Biochemistry provides an introduction to the fundamental aspects of Biochemistry. It gives an overview of the structure, function and metabolism of biologically important molecules; carbohydrates, fatty acids, proteins and nucleic acids. Enzyme kinetics, allosteric inhibition, enzyme inhibition and control are considered in detail. The course concludes with a review of amino acid metabolism. Throughout, the emphasis is placed on the regulation of metabolic pathways and on their interrelationships in health and disease etiology, diagnosis and treatment. Cell membranes and the structure, function and replication of the cell’s genetic material are described. The digestion and absorption of nutrients is reviewed and the consequences of malfunction considered. A number of disease states are used to illustrate selected principles including the relationship between nutrition and disease; atherosclerosis, hyperlipidemia, obesity and diabetes. The application of clinical biochemistry techniques to disease diagnosis is described and the biochemistry of exercise and aging visited.
