Finally, to sum up, the answer to the question: Is creatinine the same as creatine? Although creatinine and creatine have origins from the same source and relate to muscle metabolism, they perform different roles in the body. Creatinine which is a waste product should be considered to evaluate...
Creatinine is the anhydride of creatine, a compound that exists in skeletal muscle as creatine phosphate. It has a MW of 113. Conversion of creatine to creatinine is nonenzymatic and irreversible. The serum creatinine level reflects total body supplies of creatine and correlates with muscle mass.12...

Prolonged storage of the urine can also introduce error, as high temperature and low urine pH enhance the conversion of creatine to creatinine in stored urine. Therefore, urine samples should be refrigerated and the urine creatinine level measured without undue delay. View chapterExplore book ...
subject in 1926. Included in the present volume are chapters on the determination, distribution, origin and excretion of creatine and creatinine, Other chapters deal with the relation between these substances and water, energy, mineral and carbohydrate metabolism, as well as between them and the ...
This could explain the absence of demonstrable creatinine metabolism in normal subjects.5. Two pathways of metabolism were identified: a recycling of creatinine to creatine and an irreversible degradation of creatinine to products other than creatine. 展开 关键词:...

CRE: Creatine; PCR: Phosphocreatine; CREA: Creatinine; CK: Creatine kinase; P: Phosphate; ATP: Adenosine triphosphate; ADP: Adenosine diphosphate Why measure creatinine? Creatinine is measured to assess kidney dysfunction, i.e. to detect and monitor chronic kidney...
This is precisely the reason why a physiological demand for carbohydrates is much higher in a growing organism, than in an adult organism. The presence of creatine in the urine of children under one year indicates that they apparently need more carbohydrates than has been generally supposed. We ...
