creatinen.

Brit.

/ˈkriːətiːn/,

/ˈkriːətɪn/, U.S.

/ˈkriəˌtin/,

/ˈkriədən/

Forms: 1800s creatin, 1800s kreatin, 1800s kreatine, 1800s– creatine.

Origin: A borrowing from French. Etymon: French créatine.

Etymology: < French créatine (M. E. Chevreul 1832, in Jrnl. de chim. méd. 8 548) < ancient Greek κρεατ- , κρέας (see creatic adj.) + French -ine -ine suffix⁵.

Biochemistry.

A compound stored in muscle tissue in a phosphorylated form (phosphocreatine) which serves as the main source of phosphate groups for the regeneration of ATP as an energy source during muscular contraction.Creatine is methylguanidinoacetic acid; HN=C(NH₂)N(CH₃)CH₂COOH. Creatine is sometimes used as a dietary supplement to improve athletic performance.
