inactivate inactivate v. t. [imp. & p. p. {inactivated}; p. pr. & vb. n. {inactivating}.] to make inactive; as, boiling will inactivate most enzymes; acetylation of the antibiotic inactivated it.

Syn: deactivate. [WordNet 1.5 +PJC]

Note: To inactivate an enzyme or chemical usually renders it permanently inactive; to inactivate a machine (as by turning a switch) may be reversible, and for machines and devices, the term {deactivate} is usually used. The distinction is worth preserving. [PJC]
