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]

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.
