Related to phosphocreatine: creatine kinase

phosphocreatine

 (PC) [fos″fo-kre´ah-tin]
a compound of creatine and phosphoric acid occurring in muscle, being the most important storage form of high-energy phosphate, the energy source in muscle contraction.

phos·pho·cre·a·tine

(fos'fō-krē'ă-tēn),
A phosphagen; a compound of creatine (through its NH2 group) with phosphoric acid; a source of energy in the contraction of vertebrate muscle, its breakdown furnishing phosphate for the resynthesis of ATP from ADP by creatine kinase. Compare: phosphoarginine.

n.
An organic compound, C4H10N3O5P, found in muscle tissue and capable of storing and providing energy for muscular contraction. Also called creatine phosphate.

phos·pho·cre·a·tine

(PCr) (fos'fō-krē'ă-tēn)
A phosphagen; a compound of creatine with phosphoric acid; a source of energy in the contraction of vertebrate muscle, its breakdown furnishing phosphate for the resynthesis of adenosine triphosphate from adenosine diphosphate by creatine kinase.
Synonym(s): creatine phosphate, Nω-phosphonocreatine.

phosphocreatine

a compound used in the production of ATP from ADP in muscles, being converted to creatine with the release of inorganic phosphorus.

Phosphorylation of ADP is necessary for the regeneration of ATE There are only minimal ATP stores throughout the body maintained for energy, so when the ATP stores become depleted during the body's muscle contractions, phosphocreatine is then converted into creatine and ATE For an individual to have continuous muscle contraction, immediate regeneration of ATP is necessary.
