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.
