Simple Classification Of Activators

Activators are mostly ions or simple organic compounds. Activators can be divided into three categories according to molecular size: (1) inorganic ions, such as cations (mostly metal ions)(K+, Mg2+, Ca2+, etc.), anions (Br-, Cl-, etc.), hydrogen ions, etc.; (2) organic molecules, such as glutathione, ethylenediamine tetraacetic acid (EDTA); (3) Proteins and other biological macromolecules, such as enzyme activation.
It can also be divided into essential activators and non-essential activators according to whether the enzyme is changed from inactive to active. Among them, most of the metal ion activators are indispensable to the enzymatic reaction, and the activity of the enzyme can not be measured without adding it, which is an essential activator. The necessary activator itself is not converted into the product (the quality and quantity of the reaction are not changed). Non-essential activators enhance enzyme activity by binding to enzymes or substrates or enzyme-substrate complexes, while essential activators act similarly to substrates, participating in enzyme-substrate or enzyme-substrate complex binding reactions.
