Cholera is an infectious disease with diarrhoea caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. Cholera was prevalent in the UK in the 19th century before modern water and sewage treatment systems eliminated its spread by contaminated water.
Different chemical reactions are used in combinations during chemical synthesis in order to obtain a desired product. In biochemistry, a consecutive series of chemical reactions (where the product of one reaction is the reactant of the next reaction) form metabolic pathways. These reactions are often catalyzed by protein enzymes.
Inorganic chemistry is the study of the synthesis, structure and behavior of inorganic or organometallic compounds. Almost every sector of the chemical industry makes use of inorganic chemistry, including catalysis, materials science, paints and pigments, surfactants, coatings, medicines, fuels and plastics. Inorganic chemists work in academic research, the geosciences, and the mining, semiconductor and environmental science industries. A bachelor's degree is the minimum qualification for almost any career in inorganic chem, and most research and product development positions will require a master's or doctorate degree.
