What is Biology?

The word ‘bios’ means life and ‘logos’ means study. Hence, biology can be defined as the study of living organisms. It is divided into many specialized fields that cover their anatomy, ¬†behavior,¬† morphology, physiology,origin, and distribution.

What is Chemistry?

Chemistry can be defined as the study of matter, its properties, and how substances interact with energy, how and why substances combine or separate to form other substances. Many people think of that “chemists” as being white-coated scientists mixing “strange liquids” in a laboratory, but the truth is we are all chemists. Understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.

What is Biochemistry?

Basically, biochemistry is the study of the chemical processes occurring in living matter. Though, this simple definition encompasses an incredibly diverse field of research that touches nearly all aspects of lives.


One of the most pressing issues in our society, environmental degradation, is being addressed by biochemists. A few examples of work currently being performed include improvements in the efficiency of photosynthesis to increase crop yields, bioremediation of polluted soils, development of new feed-stocks, chemistries for the production of biofuels, genetic mapping of ecosystems to monitor biodiversity, and methodologies for boosting biological capture of carbon. These and other biochemical technologies may play a crucial role in our efforts to find a sustainable means of living.


Perhaps the most obvious application of biochemistry in our everyday existence is in the field of health research. Biochemistry has been a key to our growing understanding of a myriad of health issues; from diabetes to arteriosclerosis to cancer.

The tools of biochemists have identified the gene, protein and pathway disruptions that lead to disease and, in many cases, point us to preventions, treatments or cures. From aspirin to interleukins, the treatment of human disease relies heavily on biochemistry.


Many other, less obvious, aspects of our society are also being altered and improved by biochemical research. Industry is being transformed as biological chemistry is being used to generate new materials with novel properties or to improve the efficiency of older processes.

Law enforcement increasingly relies on biochemistry-based forensics to provide evidence in investigations. Archaeology is rapidly advancing as genetic and isotopic investigations of our ancestral remains are illuminating much of human history and prehistory.
