Original sentence: A chemical synthesis in this broader sense is not restricted to a single kind of chemical reaction or a single step.A chemical synthesis usually involves the use of compounds that are known as reagents or reactants.If a chemical synthesis starts from basic laboratory compounds and yields something new, it is a purely synthetic process.If it starts from a product isolated from plants or animals and then proceeds to a new compounds, the synthesis is described as a semisynthetic process.In chemistry, the phrase chemical synthesis appears to have one of two meanings.It may take multiple steps to synthesize the product of interest, and inordinate amounts of time.One meaning of chemical synthesis is the process of creating a chemical compound through a series of physical and chemical manipulations usually involving one or more chemical reactions.Skill in this area is prized among chemists and the synthesis of exceptionally valuable or difficult compounds has won chemists the Nobel Prize.The other meaning of chemical synthesis is narrow and restricted to a specific kind of chemical reaction, a direct combination reaction, in which two or more reactants combine to form a single product
Edited sentence: A chemical synthesis is a process of creating a chemical compound through a series of physical and chemical manipulations usually involving one or more chemical reactions.A chemical synthesis usually involves the use of compounds that are known as reagents.A classic example of this is the formation of egg whites (i.A common step in a chemical synthesis can involve a direct combination reaction, in which two or more reactants combine to form a single product.A → B.But a chemical synthesis can also involve transformation reactions, where the application of light or heat or other external physical factor causes a single reactant to form a single product.Chemical syntheses may also create multiple products, of which only one is the desired material.the denaturation of albumin) by the application of heat, or the formation of caramel from sugar by the application of heat
