Physiological mechanisms of creatine

WebbCreatinine is a non-protein nitrogenous compound that is produced by the breakdown of creatine in muscle. Creatinine is found in serum, plasma, and urine and is excreted by glomerular filtration at a constant rate and in the same concentration as in plasma. WebbCreatine is an organic acid that contributes to the energy supply to the skeletal muscle. The basic substrates for creatine biosynthesis in the human body are semi-essential amino acids L-arginine, glycine and methionine. In this book, the authors discuss the biosynthesis, therapeutic uses and physiological effects of creatine supplementation.

Webb9 feb. 2024 · Your body stores creatine as phosphocreatine primarily in your muscles, where it's used for energy. As a result, people take creatine orally to improve athletic performance and increase muscle mass. People also use oral creatine to treat certain brain disorders, neuromuscular conditions, congestive heart failure and other conditions. Creatine is a naturally occurring non-protein compound and the primary constituent of phosphocreatine, which is used to regenerate ATP within the cell. 95% of the human body's total creatine and phosphocreatine stores are found in skeletal muscle, while the remainder is distributed in the blood, brain, testes, and other tissues.
