Phosphocreatine (Noun)
Meaning
An organic compound of creatine and phosphoric acid; found in the muscles of vertebrates where its hydrolysis releases energy for muscular contraction.
Classification
Nouns denoting substances.
Examples
- Muscle cells store phosphocreatine as an energy reserve for times of high physical stress.
- The breakdown of phosphocreatine in muscle provides energy during short-duration activities like sprinting or weightlifting.
- In high-intensity exercise, phosphocreatine degradation can rapidly release the energy required for muscle contraction.
- ATP levels can be replenished in working muscles by the rapid hydrolysis of phosphocreatine stores.
- The metabolic pathway in which phosphocreatine is synthesized is particularly important for non-oxidative production of ATP.
