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.

The adipic acid complexes of DL-arginine and L-arginine are made up of zwitterionic, singularly positively charged arginium ions and doubly negatively charged adipate ions, with a 2:1 stoichiometry. One of the two crystallographically independent arginium ions in the L-arginine complex

Although naturally abundant amino acids are represented mainly by l-enantiomers, fermented foods are known to contain various d-amino acids. Enantiospecific profiles of food products can vary due to fermentation by bacteria, and such alterations may contribute to changes in food

The complexes of L-arginine and DL-lysine with pimelic acid are made up of singly positively charged zwitterionic amino acid cations and doubly negatively charged pimelate ions in a 2:1 ratio. In both structures, the amino acid molecules form twofold symmetric

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
