This course concerns the chemistry of Life. The evolution of living organisms started with chemical reactions and chemistry is still the basic science underlying biology. Biochemistry, the chemistry of life, deals with the chemical reactions that produce the specific moklecules of life like DNA, RNA, proteins, carbohydrates etc. that enable the self-assembly and reproduction of simple and complex organisms. Although organisms var enormously in complexity and biological properties, they al use similar types of biomolecues for encoding the transmission of information, for compartment formation (membranes), for building and degrading macromolecules, energy metabolism etc. Errors in the production, proper localization or degradation of these molecules often will cause disease. Biochemical knowledge thus is essential for understanding the molecular biology of cells, the causes  and treatment  of disease, and the possibilities of bio-technology
