L-Arginine hydrochloride

Description

L-Arginine hydrochloride is a salt form of L-Arginine, where hydrochloric acid is added to enhance stability and solubility. Arginine hydrochloride is a L-alpha-amino acid. An essential amino acid that is physiologically active in the L-form. L-Arginine might be effective at lowering blood pressure, reducing the symptoms of angina and PAD , and treating erectile dysfunction due to a physical cause.

Chemical properties

White crystalline powder

The Uses of L-Arginine hydrochloride

gastric acid depressant

The Uses of L-Arginine hydrochloride

An essential amino acid for human development. Precursor for nitric oxide. Ammonia detoxicant (hepatic failure); diagnostic aid (pituitary function).

The Uses of L-Arginine hydrochloride

L-Arginine monohydrochloride is used in the treatment of heart and circulatory diseases. It is a precursor of nitric oxide synthesis that induces vasodilation in vivo, there by relaxing blood vessels. It is also used in the treatment of angina and other cardiovascular problems. It is an important intermediate in the urea cycle and involved in the detoxification of nitrogenous wastes. It is commonly used in cell culture media and drug development.

What are the applications of Application

L-Arginine Monohydrochloride is a precursor of nitric oxide synthesis that induces vasodilation in vivo

Definition

ChEBI: Arginine hydrochloride is a L-alpha-amino acid.

brand name

R-Gene 10 (Pharmacia & Upjohn).

Biochem/physiol Actions

L-Arginine is considered as a semi essential amino acid. In most mammals including humans, L-Arginine synthesis occurs through intestinal-renal axis, from glutamine, glutamate and proline. Abnormal levels of L-Arginine is associated with the development of kidney and cardiovascular disease. L-arginine is found to decrease fat mass and visceral adiposity.

Side Effects

L-arginine has some potential side effects to consider when taking it as a supplement. Some of the more common and benign side effects can include: nausea, diarrhea, bloating, and abdominal pain. However, L-arginine may result in some serious complications.

Safety Profile

Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. An experimental teratogen. When heated to decomposition it emits very toxic fumes of NOx and HCl.

Purification Methods

A likely impurity is ornithine. Crystallise the salt from H2O at pH 5-7, by adding EtOH to 80% (v/v). [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 p 1841 1961, Beilstein 4 IV 2649.]
