Irreversible inhibition definition

WebIrreversible enzyme inhibition is the alteration of an enzyme by any compound referred to as an inhibitor that tends to stop the chemical reaction from irreversibly forming the products. Overview of Irreversible Enzyme Inhibition A protein inhibitor is any compound that connects to a catalyst and results in declining its action. WebFeb 21, 2016 · Irreversible inhibition of, say, a cell surface receptor means that a drug (agonist/antagonist) binds permanently to the target receptor, usually by binding covalently; the chemical reaction is not reversible. This isn't synonymous with a permanent effect on a cell or organism; that depends on turnover of the receptor.
