L-arginine Oil Introduction
Arginine foods (abbreviated as Arg or R) are alpha-amino acids for the biosynthesis of proteins. It is encoded by the codons CGU, CGC, CGA, CGG, AGA and AGG. The arginine supplement contains an α-amino group, an α-carboxylic acid group and a side chain composed of a 3-carbon aliphatic straight chain terminated with a thiol group. At physiological pH, the carboxylic acid is deprotonated (-COO-), the amino group is protonated (-NH3 +), and the sulfhydryl group is also protonated to give the phosphonium salt form (-C-(NH2)2+), Thereby producing an arginine-charged aliphatic amino acid. It is a precursor to nitric oxide biosynthesis.
In humans, arginine hcl 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 can be synthesized in the body from glutamine via citrulline.
Arginine is an essential amino acid for the growth and development of infants and young children. It is an intermediate metabolite of the ornithine cycle that promotes the conversion of ammonia to urea, thereby reducing blood ammonia levels. It is also a major component of sperm protein, which promotes sperm production and provides sperm motility. In addition, intravenous injection of arginine, can stimulate the pituitary release of growth hormone, can be used for pituitary function test.
It can be used as a nutritional supplement. Arginine is a component of the ornithine cycle and has extremely important physiological functions. Eating more arginine can increase the activity of arginase in the liver and help to The ammonia in the blood is converted to urea and excreted. Therefore, arginine is associated with hyperammonemia, liver dysfunction, etc.
L-arginine is also the main component of sperm protein, which promotes the quality of sperm and enhances the energy of sperm movement.
Arginine can effectively improve immunity and promote the secretion of endogenous substances such as natural killer cells, phagocytic cells and interleukin-1 by the immune system, which is beneficial to fight cancer cells and prevent viral infection. Further, arginine is a precursor of L-ornithine and L-valine. Proline is an important component of collagen. Supplementation of arginine is helpful for protecting large amounts of tissue repair and has the effect of reducing infection and inflammation.

L-arginine dosage is an amino acid that has numerous functions in the body.
Blood vessel function:
In the body, L-arginine is used to make nitric oxide, which reduces blood vessel stiffness, increases blood flow, and improves blood vessel function.
L-arginine has been used for erectile dysfunction. Like the drug sildenafil citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide, which relaxes muscles surrounding blood vessels supplying the penis. As a result, blood vessels in the penis dilate, increasing blood flow, which helps maintain an erection.
L-arginine's possible activity in wound repair may be due to its role in the formation of L-proline, an important amino acid that is essential for the synthesis of collagen.
Other arginine function Conditions:
L-arginine is also used for high blood pressure, migraines, sexual dysfunction in women, intermittent claudication, and interstitial cystitis.
1. It can be used for adjuvant treatment of physiological abnormalities caused by endothelial cell dysfunction.
2. It can improve the body's immune function.
3. It can be used for adjuvant treatment of unstable angina.
4. It can be used as an adjuvant treatment for growth hormone deficiency in children.
5. It can help increase the number of male sperm.
