L-Alanine is a non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and the central nervous system. BCAAs are used as a source of energy for muscle cells. During prolonged exercise, BCAAs are released from skeletal muscles and their carbon backbones are used as fuel, while their nitrogen portion is used to form another amino acid, Alanine. Alanine is then converted to Glucose by the liver. This form of energy production is called the Alanine-Glucose cycle, and it plays a major role in maintaining the body's blood sugar balance.
L-Alanine is a white and odorless crystal powder with special sweet tasle, which degree is about 70% of sugar. It easily dissolves in water (17% under 25), slightly dissolves in alcohol (0.2% in cold alcohol) and unclissolves in ether. PH value in 5% water solution equals 5.5 to 7.0.
L-Alanine is a kind of important amino acid formed proteins. In medicine, it is a main material syntheslsed VB6, composition of nutriments, and important composition of 800-14 amino acid injection new medicine for disease of liver and brain. In food, it can be used as flavouring, synthetic sweet agent and improving the aidity of organic acid. Also it can be used as additive of salted food, drink cotained alcohlos, oil, yolk sauce, and improving the taste of food made with dregs of rice.
L-Alanine research information
L-Alanine molecular expressions: The amino acid collection - The alpha-carbon in alanine is substituted with a levorotatory (l)-methyl group, making it one of the simplest amino acids with respect to molecular structure. This amino acid is one of the most widely used in protein construction, averaging about 9 percent of average protein composition on a per-mole basis when compared with the other amino acids. Alanine has little therapeutic role in humans, although it has been demonstrated to display a cholesterol-reducing effect in rats.
Glossary definition for alanine (non-essential amino acid) - An important source of energy for muscle tissue, the brain and central nervous system; strengthens the immune system by producing antibodies; helps in the metabolism of sugars and organic acids.
The glucose-alanine cycle - The glucose-alanine cycle is used primarily as a mechanism for skeletal muscle to eliminate nitrogen while replenishing its energy supply. Glucose oxidation produces pyruvate which can undergo transamination to alanine.
