L - Arginine Amino Acid Powder for Erectile dysfunction and High blood pressure CAS 74-79-3
Arginine ( abbreviated as Arg or R ) encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG is an α-amino acid that is used in the biosynthesis of proteins.
Arginine is classified as a semiessential or conditionally essential amino acid, depending on the developmental stage and health status of the individual. Preterm infants are unable to synthesize or create arginine internally, making the amino acid nutritionally essential for them. Most healthy people do not need to supplement with arginine because it is a component of all protein-containing foods and their body produces sufficient amounts.
Arginine was first isolated from a lupin seedling extract in 1886 by the German chemist Ernst Schultze. It contains an α-amino group ( which is in the protonated −NH3+ form under biological conditions ), an α-carboxylic acid group ( which is in the deprotonated −COO− form under biological conditions ), and a side chain of a 3-carbon aliphatic straight chain capped by a complex guanidinium, classifying it as a charged ( at physiological pH ), aliphatic amino acid.
Arginine plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones.
The roles of endogenous arginine include:
Precursor for the synthesis of nitric oxide.
Healing of injuries, possibly through mTOR protein kinase.
Regulate blood pressure.
The distributing basics of the moderate structure found in geometry, charge distribution, and ability to form multiple H-bonds make arginine ideal for binding negatively charged groups. For this reason, arginine prefers to be on the outside of the proteins, where it can interact with the polar environment.
Incorporated in proteins, arginine can also be converted to citrulline by PAD enzymes. In addition, arginine can be methylated by protein methyltransferases.
Arginine is the immediate precursor of nitric oxide ( NO ), urea, ornithine, and agmatine; is necessary for the synthesis of creatine; and can also be used for the synthesis of polyamines ( mainly through ornithine and to a lesser degree through agmatine ), citrulline, and glutamate. As a precursor of nitric oxide, arginine may have a role in the treatment of some conditions where vasodilation is required. The presence of asymmetric dimethylarginine ( ADMA ), a close relative, inhibits the nitric oxide reaction; therefore, ADMA is considered a marker for vascular disease, just as L-arginine is considered a sign of a healthy endothelium.
L-arginine is generally recognized as safe ( GRAS-status ) at intakes of up to 20 grams per day.
