The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.he general concept of a chemical reaction has been extended to reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.
  The substances used up in a reaction are the reactants. The new substances made are called the products.   The terms reactant and product can be used to describe cons â¦ tituents of individual enzymatic reactions or entire metabolic pathways.eactants are the substances used in a chemical reaction, usually on the left side of the reaction arrow.
