Acid-Base Catalysis
In enzyme-mediated catalysis, general acid-base catalysis occurs when an acidic or basic residue at the active site is used to facilitate proton transfers in the reaction. As an example of general acid-base (and covalent) catalysis.
Double Displacement Reactions (Salt Metathesis)
Double displacement reactions are also known as salt metathesis reactions or double replacement reactions. Like any other chemical reaction, these chemical reactions also involve the conversion of certain chemical compounds (ionic or covalent) into a new chemical compound.
