Guanosine is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. L-Guanosine is the L configuration of Guanosine.

L-Gulono-1,4-lactone is a substrate of L-gulono-1,4-lactone oxidoreductase, which catalyzes the last step of the biosynthesis of L-ascorbic (Vatamin) C. In other words, L-Gulono-1,4-lactone is a direct precursor of vitamin C in animals, in plants and in some protists.

L-Histidinol dihydrochloride is an endogenous metabolite.

L-Homocitrulline is an amino acid and a metabolite of ornithine in mammalian metabolism.

L-Homocysteine, a homocysteine metabolite, is a homocysteine that has L configuration. L-Homocysteine induces upregulation of cathepsin V that mediates vascular endothelial inflammation in hyperhomocysteinaemia .

L-Hydroxyproline is a versatile reagent for the synthesis of neuroexcitatory kainoids[1] and antifungal echinocandins.

Isovaline L- is an amino acid.

L-Kynurenine is a metabolite of the amino acid L-tryptophan. L-Kynurenine is an aryl hydrocarbon receptor agonist.

Nitroarginine, or Nω-nitro-L-arginine, is a nitro derivative of the amino acid arginine. It is an inhibitor of nitric oxide synthase and hence a vaso-constrictor and coronary constrictor. As such, it finds widespread use as a biochemical tool in the study of nitric oxide and its biological effects. Nitroarginine has been used in research studying coronary […]
