- During intense exercise, phosphocreatine donates a phosphate group to ADP to rapidly regenerate ATP.
Variants and Related Words
- Creatinine (n): A breakdown product of creatine phosphate in muscle, typically excreted in urine and used as an indicator of kidney function.
- Elevated creatinine levels in the blood can suggest impaired kidney function.
Synonyms
- N-(aminoiminomethyl)-N-methylglycine: The systematic IUPAC name for creatine.
