Use	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 the main component of sperm protein, which promotes sperm production and provides energy for sperm movement. In addition, intravenous arginine, can stimulate the pituitary growth hormone release, can be used for pituitary function test.

arginine is a semi-essential amino acid in the human body, that is, an amino acid that is less synthesized in the human body and needs to be partially supplemented from food, but is essential for maintaining the growth and development of infants. In the body it is an intermediate metabolite of the ornithine cycle, can promote the production and excretion of urea, correct ammonia poisoning and can relieve hepatic coma. Arginine is also the main component of sperm protein, which can promote sperm production and improve sperm movement energy. Widely found in pig hair, hoof nails, blood meal, gelatin, protamine, small miscellaneous fish.

Open Data Verified Data

attention should be paid to the occurrence of hyperchloremic acidosis in patients with renal dysfunction and anuria or in large doses. Too fast infusion can cause salivation, facial flushing and Vomit. Renal insufficiency or anuria with caution or disabled. Explosive liver failure, the lack of arginase, should not be used. When the liver function is not good, the enzyme activity required in the ornithine circulation is reduced, and the effect of reducing blood ammonia is not obvious.

essential amino acids	L-arginine is a coding amino acid in protein synthesis, which belongs to one of the 8 essential amino acids in human body. The body needs it to perform multiple functions. For example, it stimulates the body to release specific chemicals such as insulin and human growth hormone. This amino acid also helps to remove ammonia from the body and promotes wound healing. It is also required for the production of sarcosine by the human body. Nitric oxide is produced when L-arginine is broken down, thus dilating vascular disease and increasing blood flow. Normally, the body itself produces enough L-arginine. But in case of deficiency, it can be supplemented by eating foods rich in arginine. L-arginine can be found in any protein-containing food, such as meat, poultry, cheese products, fish, etc. Arginine-rich foods include almonds, walnuts, dried sunflower kernels, dark chocolate, chickpeas, melon, peanuts, green lentils, hazelnuts, Brazil nuts, red meat (moderate), cashew nuts, salmon, pistachio, soy and walnut. This year, many people have taken L-arginine supplements to treat certain diseases, such as congestive heart failure and cystitis. Although there are many benefits, but there are also some potential side effects, such as Abdominal Pain, Diarrhea, gout and abdominal distension, and may increase the severity of herpes outbreaks and strengthen the effect of antihypertensive drugs, causes a decrease in blood pressure beyond the expected range, causing dizziness and fainting in hypertensive patients.
identification test	take 0.1% ml of sample solution and add 1 ml of ninhydrin test solution (TS-250), which should be reddish purple.

production method	with gelatin or pig hair, pig blood powder as raw materials, after hydrolysis, the acid hydrochloride is extracted from the hydrolysate (see 03400) and the hydrochloric acid is removed to obtain the final product. From protein (e. G., gelatin) hydrolysates by ion exchange resin or barium hydroxide separation. It is usually made into hydrochloride, but it is also stable in the Free State, so there are also free products for sale. It can also be obtained by fermentation using sugars as raw materials. with gelatin as raw material, after hydrochloric acid hydrolysis and condensation with benzaldehyde, benzylidene arginine was obtained, which was purified by hydrochloric acid hydrolysis, activated carbon treatment and column chromatography.
