making muscle wasting history

Creatine kinase, also known as phosphocreatine kinase or creatine phosphokinase, is an enzyme or a type of protein that is found in several tissue types of the human body, including the muscle and the brain. The function of this enzyme is to catalyze the conversion of creatine to phosphocreatine by applying itself in the consumption of adenosine triphosphate, the generation of adenosine diphosphate, and the reverse reaction. Adenosine triphosphate is a vital source of energy in biochemical reactions; in the skeletal muscle, the brain, and the smooth muscle.

There are three types of creatine kinase or isoenzymes in the body: CK-BB is mainly produced by the brain and the smooth muscle; CK-MB is primarily produced by the heart muscle; and most of CK-MM is produced by the skeletal muscle.

In normal conditions, there is very little creatine kinase circulating in the blood of the average, healthy human being. Taking the creatine test is a good idea to find out where exactly it is that one stands when it comes to the prevalent level of creatine kinase in the body. The test specifically measures the blood levels of certain muscle and brain enzyme proteins; the normal results for females range between 10 – 79 units per liter (U/L) and 17 – 148 U/L in males.

If the test reveals that the level of creatine kinase circulating in the blood is higher than it should be in normal conditions, then chances are that the human body in question has suffered damage either to the muscle or the brain. In fact, astronomical levels of creatine kinase are indicative of injuries, rhabdodomyolysis, myocardial infarction, myocarditis, myositis, malignant hypethermia, McLeod syndrome, neuroleptic malignant syndrome, and hypothyroidism.

Experts suggest that anyone who is not sure whether or not they have had a heart attack (which is hard to imagine!) or whether muscles in their bodies have been damaged as a result of any sort of activity, should make it a point to go for a creatine kinase test. This group also includes those with chest pain, muscle pain, and any sort of muscle weakness
Normally the creatine kinase lives within the muscule in a healthy person whereas in duchenne boys creatine kinase tends to leak out of damaged muscle.
