单词 orotate
释义

orotaten.

Brit. /ˈɒrəteɪt/, U.S. /ˈɔrəˌteɪt/
Origin: Formed within English, by derivation; perhaps modelled on an Italian lexical item. Etymons: orotic adj., -ate suffix1.
Etymology: < orot- (in orotic adj.) + -ate suffix1, perhaps after Italian orotato (see below).Quot. 1905 is from an abstract of an Italian paper (G. Biscaro & E. Belloni 1905, in Ann. della Soc. Chim. di Milano 11 25), but it has not been possible to verify whether Italian orotato is used in this text. Compare German Orotat (in Silberorotat silver orotate (1905 in an abstract of the same Italian paper)).
Biochemistry.
A salt or ester, or the anion, of orotic acid.
