Application

DL-Arginine hydrochloride (DL-Arg) is a racemic mixture of the natural proteinogenic amino acid L-arginine and the non-proteinogenic D-arginine. DL-Arg is used in physicochemical analysis of amino acid complexation dynamics and crystal structure formations.

Substrates

Substrate for nitric oxide synthetase; induces insulin release by a nitric oxide-dependent mechanism.

d-Amino acids have recently attracted much attention in various research fields including medical, clinical and food industry due to their important biological functions that differ from l-amino acid. Most chiral amino acid separation techniques require complicated derivatization procedures in order
