WebOct 1, 2024 · Irreversible Inhibition — An inhibitor chemically modifies the enzyme, usually by forming covalent bonds with the R-groups of certain amino acids. The interaction … WebJan 3, 2024 · An inhibitor of this type is known as a competitive inhibitor. In some cases, the inhibitor chemically reacts with the enzyme, forming a covalent bond. This type of inhibitor is essentially irreversible, so that increasing substrate concentration does not overcome inhibition. These are therefore known as non-competitive inhibitors. flvto online mp3 converter
