Biochemistry is at the interface of chemistry and biology. It is the study of the chemistry processes in living organisms. At a fundamental level, this discipline incorporates the analysis of both the functional and structural roles of macromolecules (such as nucleic acids, enzymes, hormones, proteins and fats) with the study of how these compounds interact to influence cell biology or the external environment. The study of biochemistry reveals the complexity of even the simplest system, through the analysis of these reaction pathways. The knowledge gained from fundamental biochemical studies is translated into applied research to understand human and animal diseases, inform drug development, understand chemical toxicity and remediate the environment. There are a number of research and teaching themes in the department, including environmental and medical biochemistry. In addition, students are trained in the essential practical techniques required to conduct independent biochemical research.
Microbiology is the study of microbes that are mostly too small to observe with the naked eye. These include viruses, bacteria, yeast and fungi. Many different microbes exist and they can be beneficial contributing to the cycling of nutrients in the environment, degradation of harmful substances and assisting in the manufacture of antibiotics, food and beverage products. Some microbes are harmful causing food spoilage, fouling and diseases of humans, animals and crops. Microbiology at Rhodes University covers fundamental aspects of microbes, delving into their molecular secrets and how these fundamental aspects can be applicable to industry and the environment.
