Biochemistry is a branch which is concerned with the chemistry of the biological processes. The study of biochemistry deals with the chemical combinations and reactions which take place in biological processes such as growth, metabolism, reproduction, heredity etc., as well as the effect of the environment on living organisms. Studying Structures and functions of enzymes, proteins, carbohydrates, fats, process of metabolism and the molecular basis of the action of genes also form a part of biochemistry. Advances made in biochemistry has made significant contributions towards elucidation and understanding of the DNA Structure. Biochemists work in many walks of life in industry, hospitals, agriculture, research institutes, education and associated areas. There are many areas of everyday life as diverse as medical products and diagnostics, new food and its safety, crop improvement, cosmetics and forensic science that owe their development or even existence to biochemists.
