L-Arginine Monohydrochloride - Nature
Open Data Verified Data
- This product is white crystalline powder; Odorless; Bitter taste. Soluble in water, aqueous solution acidic reaction. Very slightly dissolved in ethanol. The decomposition temperature is 23 5 deg C.
- This product is the hydrochloride of L-arginine. Arginine is a semi-essential amino acid that is less synthesized in the human body and needs to be partially supplemented from food. In the body it is an intermediate metabolite of ornithine cycle, can promote the production and excretion of urea, correct ammonia poisoning and can relieve hepatic coma. Arginine is the main component of sperm protein, and also has the function of promoting sperm production and providing sperm movement energy. In nature, it widely exists in pig hair, hoof nails, blood meal, gelatin, protamine, small miscellaneous fish. Due to the strong alkalinity of arginine aqueous solution, it absorbs carbon dioxide from the air and is made into hydrochloride.
