L-Arginine product description
Product description
L-Arginine (L-1-Amino-4-guanidovaleric acid)
Molecular formula: C6H12N4O2 Molecular Weight: 174.2
Properties: White orthorhombic (dihydrate) crystals or white crystalline powder. Melting point of 244 ° (decomposition). The water of crystallization, the loss of crystal water at 105 degrees. Was dissolved in the water, the machine can hand carbon dioxide from the air. Soluble in water, insoluble in ether, slightly soluble in ethanol.
For adult non-essential amino acids, but to teach the body to generate speed slow, as the essential amino acids for infants and young children, have a detoxification role.
Natural materials abound in protamine, etc., is also the basic components of proteins, so there is very extensive.
