Chemistry is referred to as the central science because it deals with the composition and properties of all types of matter, which are all composed of chemical elements. Chemical knowledge of matter is essential to understanding other branches of science, such as physics and biology.
Chemistry is subdivided into numerous branches, including organic chemistry and biochemistry. These disciplines have a wide variety of industrial and scientific applications. Organic chemistry principles are used by the petrochemical industry in the distillation of raw materials. Knowledge of biochemistry – the study of atoms and molecules in living organisms – is necessary for the development of products ranging from food additives to cleaning fluids.
