Creatine-alpha Ketoglutarate
Creatine-alpha-ketoglutarate is a salt formed from alpha-ketoglutaric acid (AKG) and creatine. Creatine is a mass-produced fitness supplement that is supposed to increase the user's muscle mass, strength and power. Creatine requires a delivery system for cell uptake. An example is arginine alpha-ketoglutarate. Arginine alpha-ketoglutarate itself is a chemical compound that is supposed to increase the blood flow to muscles and therefore, increase nutrient delivery to muscle cells. Alpha-ketoglutarate (α-KG or AKG) itself is a central molecule in the Krebs cycle that controls the organism's overall citric acid cycle rate. It can improve bone tissue development in the skeletal muscles by decreasing protein catabolism and increasing protein synthesis. The supplement industry has theorized that binding creatine to alpha-ketoglutarate could show significant improvements in creatine delivery and uptake which would ultimately lead to greater improvements in muscle mass and performan ...

Salt (chemistry)
In chemistry, a salt is a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt, with positively charged sodium ions and negatively charged chloride ions. The component ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (). Types of salt Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called ''alkali salts'' and salts that produce hydrogen ions when dissolved in water are called ''acid salts''. ''Neutral salts'' are those salts that are neither acidic nor basic. Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered salts. Examples of zwitterions are amino acids, many metabolites, peptid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creatine
Creatine ( or ) is an organic compound with the nominal formula (H2N)(HN)CN(CH3)CH2CO2H. It exists in various modifications (tautomers) in solution. Creatine is found in vertebrates where it facilitates recycling of adenosine triphosphate (ATP), primarily in muscle and brain tissue. Recycling is achieved by converting adenosine diphosphate (ADP) back to ATP via donation of phosphate groups. Creatine also acts as a buffer. History Creatine was first identified in 1832 when Michel Eugène Chevreul isolated it from the basified water-extract of skeletal muscle. He later named the crystallized precipitate after the Greek word for meat, κρέας (''kreas''). In 1928, creatine was shown to exist in equilibrium with creatinine. Studies in the 1920s showed that consumption of large amounts of creatine did not result in its excretion. This result pointed to the ability of the body to store creatine, which in turn suggested its use as a dietary supplement. In 1912, Harvard Univer ...

Arginine Alpha-ketoglutarate
Arginine ''alpha''-ketoglutarate (AAKG) is a salt of the amino acid arginine and ''alpha''-ketoglutaric acid. It is marketed as a bodybuilding supplement. Peer-reviewed studies have found no increase in muscle protein synthesis or improvement in muscle strength from use of AAKG as a dietary supplement A dietary supplement is a manufactured product intended to supplement one's diet by taking a pill, capsule, tablet, powder, or liquid. A supplement can provide nutrients either extracted from food sources or that are synthetic in order .... References {{DEFAULTSORT:Arginine Alphaketoglutarate Bodybuilding supplements ...

Krebs Cycle
The citric acid cycle (CAC)—also known as the Krebs cycle or the TCA cycle (tricarboxylic acid cycle)—is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or aerobic respiration. In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest components of metabolism and may have originated abiogenically. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three alternative segments of the citric acid cycle have been recognized. The name of this metabolic pathway is derived from the citric acid (a tricarbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
