Description:

 
L-arginine is one of the eight essential amino acids in protein synthesis. The body needs it to perform many functions. For example, it stimulates the release of certain chemicals, such as insulin and human growth hormone. The amino acid also helps remove ammonia from the body and promotes wound healing. The body needs it to produce sarcosine. Nitric oxide is produced when L-arginine is broken down, so it can dilate vascular disease and increase blood flow. Normally, the body itself produces enough L-arginine. However, 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, melons, peanuts, raw lentils, hazelnuts, Brazil nuts, red meat (moderate), cashew nuts, salmon, pistachios, soybeans and walnuts. In recent years, many people have taken L-arginine health care products to treat certain diseases, such as congestive heart failure and cystitis.
 
 
L-Cysteine hydrochloride monohydrate Usage And Synthesis
  • Chemical Properties white crystalline powder
  • UsesL-Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. L-Cysteine is commonly use d as a precursor in the food and pharmaceutical industries. L-Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.
  • Definition ChEBI: A hydrate that is the monohydrate form of L-cysteine hydrochloride.
  • Purification MethodsLikely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
 
L-Cysteine is a crystalline free-form amino acid that is active in many body processes. L-Cysteine works in the liver to protect the body from harmful substances and may help to prevent oxidation of tissues. L-Cysteine, along with L-glutamic acid and glycine, is the rate-limiting precursor in the synthesis of glutathione peroxidase (one of the body's main antioxidant enzymes), which minimizes lipid peroxidation (fats turning rancid).
