Chemical Reaction

A chemical reaction is a process which ends in the interconversion of chemical subtances. The substance or substances involved are called reactants. These chemical reactions are usually chracterised by a chemical change a usually yield one or more products. Classically, these changes strictly involve the motion of electrons in forming and breaking of chemical bonds. Though the concept of a chemical reaction, in the particular notion of a chemical equasion is applicable to transformations of elementary particles, as well as nuclear reactions.

Different chemical reactions are used with chemical sythesis in order to get a desired product. In biochemistry, series of chemical reactions catalyzed by enzymes form metabolic pathways, by which syntheses and decompositions ordinarily impossible in conditions within a cell are performed.
