General description

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

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.

X-ray studies on crystalline complexes involving amino acids and peptides. XLI. Commonalities in aggregation and conformation revealed by the crystal structures of the pimelic acid complexes of L-arginine and DL-lysine.

N T Saraswathi et al.

Acta crystallographica. Section B, Structural science, 59(Pt 5), 641-646 (2003-10-31)

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

X-ray studies on crystalline complexes involving amino acids and peptides. XLII. Adipic acid complexes of L- and DL-arginine and supramolecular association in arginine-dicarboxylic acid complexes.

Siddhartha Roy et al.

Acta crystallographica. Section B, Structural science, 61(Pt 1), 89-95 (2005-01-22)

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

Investigation of storage time-dependent alterations of enantioselective amino acid profiles in kimchi using liquid chromatography-time of flight mass spectrometry.

Moyu Taniguchi et al.

Journal of bioscience and bioengineering, 124(4), 414-418 (2017-06-02)

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

Development of a liquid chromatography-tandem mass spectrometry method for quantitative analysis of trace d-amino acids.

Yosuke Nakano et al.

Journal of bioscience and bioengineering, 123(1), 134-138 (2016-08-21)

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

Fast enantiomeric separation of amino acids using liquid chromatography/mass spectrometry on a chiral crown ether stationary phase.

Kohei Yoshikawa et al.

Journal of bioscience and bioengineering, 130(4), 437-442 (2020-07-04)

Fast enantiomeric separation of amino acids was studied by liquid chromatography/mass spectrometry (LC/MS) on a chiral crown ether stationary phase. A chiral crown ether bonded silica column (3 mm internal diameter (i.d.), 5 cm long) packed with 3 μm particles was employed instead
