creatininen.

Brit.

/krɪˈatᵻniːn/, U.S.

/kriˈædəˌnin/

Forms: 1800s kreatinine, 1800s– creatinine.

Origin: Formed within English, by derivation; apparently modelled on a German lexical item. Etymons: creatine n., -ine suffix⁵.

Etymology: < creatine n. + -ine suffix⁵, apparently after German Kreatinin (apparently used by J. Liebig in a source translated from manuscript in quot. 1847). N.E.D. (1893) gives the pronunciation as (kriˌæ·tinəin) /kriːˈætɪnaɪn/.

Biochemistry.

A basic crystalline compound which is a product of the metabolic breakdown of creatine and is a normal constituent of urine.Creatinine is a heterocyclic imine: C₄H₇N₃O.
