Exempel på hur man kan använda PHOSPHOCREATINE i en mening

• Creatinine itself is produced via a biological system involving creatine, phosphocreatine (also known as creatine phosphate), and adenosine triphosphate (ATP, the body's immediate energy supply).
• Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.
• In the late 1920s, after finding that the intramuscular stores of creatine can be increased by ingesting creatine in larger than normal amounts, scientists discovered phosphocreatine (creatine phosphate), and determined that creatine is a key player in the metabolism of skeletal muscle.
• CK catalyses the conversion of creatine and uses adenosine triphosphate (ATP) to create phosphocreatine (PCr) and adenosine diphosphate (ADP).
• Possible physiological advantages from RSH include compensatory vasodilation and regeneration of phosphocreatine (PCr).
• Generally, there are two types of phosphagens in animals, phosphoarginine (PA) in invertebrates and phosphocreatine (PC) in vertebrates.
• When the phosphagen system has been depleted of phosphocreatine (creatine phosphate), the resulting AMP produced from the adenylate kinase (myokinase) reaction is primarily regulated by the purine nucleotide cycle.
• When the phosphagen system (ATP-PCr) has been depleted of phosphocreatine (creatine phosphate), the purine nucleotide cycle also helps to sustain the myokinase reaction by reducing accumulation of AMP produced after muscle contraction in the below reaction.
• This is done by the enzyme creatine phosphokinase which transduces energy from the transport molecule of phosphocreatine to the useful molecule for contraction demands, ATP, an action performed by ATPase in the myofibril.
