Chemical modification is a term used in chemistry in which a chemical substance is altered through a chemical reaction. There are many synonyms for this process, including chemical transformation, chemical alteration, chemical conversion, chemical modification, and chemical metamorphosis. Although they all refer to the same process, each synonym has its own specific connotations. For example, metamorphosis implies a complete change, while conversion implies a change in form. Modification implies a change that is less drastic than metamorphosis but more significant than transformation. Regardless of the specific term used, chemical modification is an essential process in many fields, including pharmaceuticals, materials science, and biotechnology.
