protonatev.

Brit.

/ˈprəʊtəneɪt/, U.S.

/ˈproʊdəˌneɪt/

Origin: Formed within English, by derivation. Etymons: proton n., -ate suffix³.

Etymology: < proton n. + -ate suffix³. Compare slightly earlier protonated adj., protonation n.

Chemistry.

transitive. To transfer a proton to (a substance, molecule, group, etc.), so that a coordinate bond to the proton is formed. Frequently in passive. Also intransitive: to receive or accept a proton in this way; to undergo protonation. Cf. earlier protonated adj.
