Amino acids

H-Tyr-OMe (Standard) is the analytical standard of H-Tyr-OMe (HY-W007671). This product is intended for research and analytical applications. H-Tyr-OMe is an amino acid derivative and also a coordinating ligand for Cu^II ions. H-Tyr-OMe can serve as a surface functionalization reagent for carbon dots, and is used to prepare fluorescent probes for biothiol sensing. H-Tyr-OMe is oxidized to quinone under the catalysis of Tyrosinase via its phenolic hydroxyl group, which quenches the fluorescence of carbon dots. H-Tyr-OMe contains potential coordination sites, including carboxyl, amino and phenolic hydroxyl groups.

L-Cystathionine is a nonprotein thioether and is a key amino acid associated with the metabolic state of sulfur-containing amino acids. L-Cystathionine protects against Homocysteine-induced mitochondria-dependent apoptosis of vascular endothelial cells (HUVECs). L-Cystathionine plays an important role in cardiovascular protection.

3-Amino-4-methylpentanoic acid is a β amino acid and positional isomer of L-leucine which is naturally produced in humans via the metabolism of L-leucine by the enzyme leucine 2,3-aminomutase. 3-Amino-4-methylpentanoic acid is also a metabolite produced by Torulaspora delbrueckii and can be used in the research of wine fermentation.

L-Lysine (acetate) (Standard) is the analytical standard of L-Lysine (acetate). This product is intended for research and analytical applications. L-Lysine acetate is an essential amino acid. L-Lysine acetate can be research for vascular calcification (VC) and Acute pancreatitis.

D-arginine (H-D-Arg-OH) is the D-isomer of arginine. Arginine is an α-amino acid that is used in the biosynthesis of proteins. D-Arginine is an inactive form of L-arginine. D-arginine can be used in myeloma and neurological disease research..

N-Acetyl-L-phenylalanine (Standard) is the analytical standard of N-Acetyl-L-phenylalanine. This product is intended for research and analytical applications. N-Acetyl-L-phenylalanine (N-Acetylphenylalanine), the principal acylamino acid in Escherichia coli, is synthesized from L-phenylalanine and acetyl-CoA.

DL-Tyrosine (Standard) is the analytical standard of DL-Tyrosine (HY-Y0123). This product is intended for research and analytical applications. DL-Tyrosine is an aromatic nonessential amino acid synthesized from the essential amino acid phenylalanine. DL-Tyrosine is a precursor for several important neurotransmitters (epinephrine, norepinephrine, dopamine).

D-Lysine monohydrochloride (Standard) is the analytical standard of D-Lysine monohydrochloride (HY-Y1804). This product is intended for research and analytical applications. D-Lysine monohydrochloride is the D-enantiomer of L-Lysine (HY-N0469). D-Lysine monohydrochloride is metabolically inert and not utilized for protein synthesis by mammalian ribosomes. D-Lysine monohydrochloride blocks renal uptake of ¹¹¹In/⁹⁰Y-Octreotide (HY-P0036)-based probes without inhibiting uptake by tumor/receptor tissues, and thus acts as a renoprotective agent in diagnostic imaging and peptide receptor radionuclide therapy (PRRT). D-Lysine monohydrochloride specifically inhibits the early steps of non-enzymatic glycation by competing with glucose via its free amino group, theoretically, it can serve as a glycation competitor that "does not interfere with protein synthesis" under chronic hyperglycemia in diabetes. D-Lysine monohydrochloride can be used in research related to cancer and diabetes.
