l-tyrosine

L-Tyrosine ((S)-Tyrosine) is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine, considered a non-essential amino acid. L-Tyrosine(L-p-Tyrosine) is the levorotatory isomer of the aromatic amino acid tyrosine.

(-)-N-[3',4'-Dihydroxy-(E)-cinnamoyl]-L-tyrosine (Caffeoyl-N-tyrosine) is an N-phenylacryloyl amino acid compound that can be isolated from cocoa beans. It plays a role in the formation of cocoa flavor.

L-Tyrosine Decarboxylase, Streptococcus faecalis (EC 4.1.1.25), is a carboxy-lyase enzyme capable of cleaving carbon-carbon bonds. The L-Tyrosine Decarboxylase Apoenzyme plays a role in tyrosine metabolism and alkaloid biosynthesis. This apoenzyme uses pyridoxal phosphate as a cofactor and works with a substrate, L-tyrosine, to produce two products: tyramine and carbon dioxide.

L-Tyrosine Decarboxylase Apoenzyme, found in Streptococcus faecalis (EC 4.1.1.25), functions as a carboxy-lyase, facilitating the cleavage of carbon-carbon bonds. This enzyme is involved in tyrosine metabolism and the biosynthesis of alkaloids. It utilizes the cofactor pyridoxal phosphate and has a substrate, L-tyrosine, which it converts to the products tyramine and carbon dioxide.

3-Nitro-L-tyrosine (3-Nitrotyrosine) is the major product from the spontaneous reaction of peroxynitrite with tyrosine. Formation of nitrotyrosine can indicate the formation of peroxynitrite by a nitric oxide (NO)-dependent oxidative damage.

3-Chloro-L-Tyrosine (Chlorotyrosine), a specific marker of myeloperoxidase-catalyzed oxidation, is markedly elevated in low-density lipoprotein isolated from human atherosclerotic intima. In particular, myeloperoxidase halogenates tyrosine residues in plasma proteins and generates 3-chlorotyrosine (CY). The detection of free chlorotyrosine in blood or urine arises from the degradation of these chlorinated proteins. CY concentrations may be useful for monitoring the activation of neutrophils in asthmatic patients.

N-Acetyl-L-tyrosine (Ac-Tyr-OH) is a side chain reaction of tyrosine. It converts to tyrosine and then can be used in neurotransmitter treatment as a precursor of cathecholamine.

DL-Tyrosine is a natural product.

N-Lactoyl-Tyrosine is an amino acid derivative and endogenous metabolite, widely used in biochemical experiments and drug synthesis research.

3-Nitro-L-tyrosine ethyl ester hydrochloride [catalog number T124433] is a valuable compound for life sciences research.

Leucyl-leucyl-tyrosine is a bioactive chemical.

L-Tyrosine-13C9,15N is intended for use as an internal standard for the quantification of L-tyrosine by GC- or LC-MS. L-Tyrosine (T0493) is a non-essential amino acid.1It is produced by hydroxylation of phenylalanine by phenylalanine hydroxylase but can also be obtained from dietary sources or degradation of endogenous proteins, resulting in L-tyrosine release.1,2L-Tyrosine is a precursor in the biosynthesis of catecholamine neurotransmitters, melanins, and thyroid hormones.3Plasma, skeletal muscle, and erythrocyte levels of L-tyrosine are decreased in patients with chronic kidney disease.1

N-Pivaloyl-L-tyrosine, an N-pivaloyl amino acid ester, is a compound commonly used in various biochemical applications.

3,5-Difluoro-L-tyrosine is a functional and tyrosinase-resistant tyrosine mimic, commonly used to evaluate the substrate specificity of protein tyrosine phosphatases (PTPs).
