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.
Five Main Branches of Chemistry. The field of chemistry is basically categorized into five main branches with the other types of chemistry typically falling into one of these branches. Here is a list of those five main categories with an explanation of what each one studies and other types of chemistry that fall into each branch. Organic chemistry is basically the study of life. It involves the study of compounds that contain carbon, which is one of the basic structures of life. It also studies the composition of structures in life forms to gain a better understanding of what creates life and how it continues to form and develop.
