Creatine is an important sports supplement

Creatine was determined in 1832 when Michel Eugène Chevreul isolated it from the basified water-extract of skeletal muscle. He later on called the crystallized precipitate after the Greek word for meat, κρέας (kreas).Apart from its pharmacological results, creatine material (as a portion of unrefined protein) can be used as an indicator of meat quality.In solution, creatine remains in stability with creatinine. Creatine is a derivative of the guanidinium cation.
