WebIrreversible inhibitors covalently bind to an enzyme, and this type of inhibition can therefore not be readily reversed. Irreversible inhibitors often contain reactive functional groups … WebIrreversible inactivation: Inhibitor forms strong covalent bonds so that it cannot be dislodged. Therefore the enzyme activity lost forever. Three major types of Reversible Inhibition 1. Competitive (Inhibitor binds to Active site) 2. Non Competitive (Inhibitor binds to Allosteric site) 3. Uncompetitive Inhibition (Inhibitor binds to ES complex)
