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.
Organic chemistry is the study of compounds that contain the element carbon. This is a wide ranging topic that overlaps with other sciences like biochemistry, medicine, and materials science. Organic chemists study the properties, structure, and chemical reactions of organic compounds. lot of these compounds are used for heating and cooking. Other groups of hydrocarbons are alkenes, and alkynes. Other elements. Other elements that carbon combines with to form organic compounds include oxygen, nitrogen, sulfur, phosphorus, and boron.
