Arginine or L-Arginine
Arginine, also known as L-Arginine is an α-amino acid that is used in the biosynthesis of proteins. L-arginine is an amino acid that helps the body make proteins. It can be obtained naturally in the diet and is also found in dietary supplement form. Foods rich in L-arginine include plant and animal proteins, such as dairy products, meat, poultry, fish, and nuts.

Specifications of L-Arginine FCC Food Grade:
L-2-Amino-5-guanidinovaleric Acid
C6H14N4O2 Formula wt 174.20
CAS: 74-79-3
DESCRIPTION
L-Arginine occurs as white crystals or as a white crystalline powder. It is soluble in water, insoluble in ether, and sparingly soluble in alcohol. It is strongly alkaline, and its water solutions absorb carbon dioxide from the air.
Function: Nutrient.
REQUIREMENTS
Identification: The infrared absorption spectrum of the sample exhibits relative maxima at the same wavelengths as those of a typical spectrum as shown in the section on Infrared Spectra, using the same test conditions as specified therein.
Assay: Not less than 98.5% and not more than 101.5% of C6H14N4O2, calculated on the dried basis.
Lead: Not more than 5 mg/kg.
Loss on Drying: Not more than 1.0%.
Optical (Specific) Rotation: [α]D20°: Between +26.0° and +27.9°, calculated on the dried basis; or [α]D25°: Between +25.8° and +27.7°, calculated on the dried basis.
Residue on Ignition: Not more than 0.2%.
