BREAKING DOWN 'Exercise'
The body mass index is Specialty Endocrinology Abdominal obesity , also known as central obesity , occurs when excessive abdominal fat around the stomach and abdomen has built up to the extent that it is likely to have a negative impact on health.

The P-N bond is highly reactive. Creatine was first identified in when Michel Eugène Chevreul isolated it from the basified water-extract of skeletal muscle.
In , creatine was shown to exist in equilibrium with creatinine. This result pointed to the ability of the body to store creatine, which in turn suggested its use as a dietary supplement.
The discovery of phosphocreatine   was reported in Creatine synthesis primarily occurs in the liver and kidneys. Creatine is not an essential nutrient  as it is naturally produced in the human body from the amino acids glycine and arginine. In the first step of the biosynthesis these two amino acids are combined by the enzyme arginine: Creatine itself can be phosphorylated by creatine kinase to form phosphocreatine , which is used as an energy buffer in skeletal muscles and the brain.
Synthesis primarily takes place in the kidney and liver, with creatine then being transported to the muscles via the blood. The majority of the human body's total creatine and phosphocreatine stores is located in skeletal muscle, while the remainder is distributed in the blood , brain, and other tissues.
However, subjects happened to show the same levels after using supplements. Creatine, which is synthesized in the liver and kidneys , is transported through the blood and taken up by tissues with high energy demands, such as the brain and skeletal muscle, through an active transport system. Additionally, in most muscles, the ATP regeneration capacity of CK is very high and is therefore not a limiting factor. Genetic deficiencies in the creatine biosynthetic pathway lead to various severe neurological defects.
Deficiencies in the two synthesis enzymes can cause L-arginine: Both biosynthetic defects are inherited in an autosomal recessive manner. A third defect, creatine transporter defect , is caused by mutations in SLC6A8 and inherited in a X-linked manner.
This condition is related to the transport of creatine into the brain. Such a reaction happens when grilling or pan-frying meat. Use of creatine by healthy adults in normal dosages does not harm kidneys; its effects on the kidney in elderly people and adolescents were not well understood as of People with kidney disease, high blood pressure, or liver disease should not take creatine as a dietary supplement.
One well-documented effect of creatine supplementation is weight gain within the first week of the supplement schedule, likely attributable to greater water retention due to the increased muscle creatine concentrations.
A systematic review discredited concerns that creatine supplementation could affect hydration status and heat tolerance and lead to muscle cramping and diarrhea. Creatine taken with medications that can harm the kidney can increase the risk of kidney damage: Creatine has a fairly short elimination half-life, averaging just less than 3 hours, so to maintain an elevated plasma level it would be necessary to take small oral doses every 3—6 hours throughout the day.
As with most supplements, each person has their own genetic "preset" amount of creatine they can hold. The rest is eliminated as waste. Creatine supplementation appears to increase the number of myonuclei that satellite cells will 'donate' to damaged muscle fibers , which increases the potential for growth of those fibers. This increase in myonuclei probably stems from creatine's ability to increase levels of the myogenic transcription factor MRF4.
Creatine supplements are marketed in ethyl ester , gluconate , monohydrate , and nitrate forms. The most prevalent of these contaminants was creatinine , a breakdown product of creatine also produced by the body. Heavy metals contamination was not found to be a concern, with only minor levels of mercury being detectable.
Two studies reviewed in found no impurities. In , Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle.
