Creatine kinase wiki
Kreatin. Kreatinkinas är ett enzym som katalyserar bildandet av fosfokreatin (PCr) från kreatin och ATP. Fosfokreatin används av muskler som ett kortsiktigt energilager då allt ATP konsumerats. Det är aktivt under de första sekunderna av muskelaktivitet, innan andra energiförsörjningsmekanismer hunnit träda in Creatine itself can be phosphorylated by creatine kinase to form phosphocreatine, which is used as an energy buffer in skeletal muscles and the brain. A cyclic form of creatine, called creatinine, exists in equilibrium with its tautomer and with creatine Kreatinkinas ( CK ), även känt som kreatinfosfokinas ( CPK ) eller fosfokreatinkinas , är ett enzym ( EC 188.8.131.52 ) som uttrycks av olika vävnader och celltyper.CK katalyserar omvandlingen av kreatin och använder adenosintrifosfat (ATP) för att skapa fosfokreatin (PCr) och adenosindifosfat (ADP). Denna CK-enzymreaktion är reversibel och sålunda kan ATP genereras från PCr och ADP Creatine conversion to phosphocreatine is catalyzed by creatine kinase; spontaneous formation of creatinine occurs during the reaction. Creatinine is removed from the blood chiefly by the kidneys, primarily by glomerular filtration, but also by proximal tubular secretion. Little or no tubular reabsorption of creatinine occurs
In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group. This transesterification produces a phosphorylated substrate and ADP. Conversely, it is referred to as dephosphorylation when the phosphorylated substrate donates a phosphate group. Creatine kinase (CK), also known as phosphocreatine kinase or creatine phosphokinase (CPK) is an enzyme (EC 184.108.40.206) expressed by various tissue types. It catalyses the conversion of creatine to phosphocreatine, consuming adenosine triphosphate (ATP) and generating adenosine diphosphate (ADP) There is a mitochondrial creatine kinase (miCK) present between the inner & outer mitochondrial membranes, which phosphorylates creatine to phosphocreatine at the cost of an ATP molecule (ATP-->ADP), which is exported out the mitochondrion through the pore protein 'P' (pages 147-148) Creatine kinase isoenzymes play a central role in energy transduction in tissues with large, fluctuating energy demands, such as skeletal muscle, heart, brain and spermatozoa Total creatine kinase levels are reduced in the second trimester of pregnancy. However, they increase in late pregnancy . Health Effects of Low Creatine Kinase Levels 1) Are Linked to Fainting. Studies suggest that the more creatine kinase a person has within the normal range, the better their heart and muscles can function

Width: 100%: Height: 100 Creatine kinase (often abbreviated CK) is an enzyme that helps muscle cells and other cells with the need for rapid and constant use of energy to create chemicals that can store and release excess energy in the cells.. In most cells, adenosine triphosphate (ATP) is the chemical which provides its parts with usable energy. It is created when adenosine diphosphate reacts with oxygen and glucose.
Creatine kinase (CK), also known as creatine phosphokinase (CPK) or phosphocreatine kinase, is an enzyme (EC 220.127.116.11) expressed by various tissues and cell types.CK catalyses the conversion of creatine and uses adenosine triphosphate (ATP) to create phosphocreatine (PCr) and adenosine diphosphate (ADP). This CK enzyme reaction is reversible and thus ATP can be generated from PCr and ADP .0 Unported License.

- Creatine kinase (CK) is found in cardiac and skeletal muscle and brain. Other tissues such as kidney have low levels of enzyme activity. This test is used to investigate cardiac or skeletal muscle pathology. CK rises approximately 6 hours after myocardial infarction (MI) and may remain elevated for 36 - 48 hours
- A creatine kinase elevation is associated with damage to some muscle tissue in the body. When a muscle gets damaged, it tends to leak creatine kinase into the blood. There are many different types of creatine kinase. The creatine kinase test is useful to detect which type of the substance has leaked into the blood
