Chemical reaction

A **chemical reaction** is a fundamental process in which one or more substances (reactants) are converted into new substances (products) through the breaking and forming of chemical bonds[7][4]. In biological systems, these are called *biochemical reactions* and are essential for life, encompassing processes such as metabolism, energy production, digestion, genetic replication, and cellular signaling[1][2][10]. Enzymes act as catalysts to accelerate most biochemical reactions within living organisms by lowering activation energy requirements[1][8][10]. Chemical reactions can be classified by type—such as hydrolysis, oxidation-reduction (redox), condensation, acid-base—and occur at rates influenced by temperature and concentration of reactants[2][4][7]. However, **"chemical reaction" is not itself a molecule or therapeutic target** like an enzyme or receptor. It describes a class of processes rather than an individual protein or structure that could be targeted by drugs. Therefore: - It does **not have canonical abbreviations**, aliases relevant to drug targeting databases, - Is **not considered a therapeutic target**, - And its inclusion as such would be incorrect. If you require information on specific enzymes or proteins that catalyze chemical reactions—such as "lactase," "DNA polymerase," or "acetylcholinesterase"—those would qualify as molecular targets with structured data available for drug discovery purposes[1][8].
