L-Tyrosine-13C9,15N is used as an internal standard for quantitative analysis of L-tyrosine by gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry. L-Tyrosine is a non-essential amino acid.

N,N-Dihydroxy-L-tyrosine is a nucleoside metabolite.

(-)-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.

N-Acetyl-L-tyrosine ethyl ester (ATEE) is a compound frequently used as a food flavoring agent and supplement. It is an ester of tyrosine, an amino acid found in various proteins. ATEE imparts sweetness, nuttiness, and a caramel-like flavor, enhancing the taste of baked goods, dairy products, and beverages. It also offers potential health benefits, such as antioxidant properties and the ability to improve cognitive function.

Lactoyl-L-tyrosine is an amino acid derivative found in the maturation process of Parmesan cheese. It can be utilized to study flavor development during cheese aging or serve as a natural flavor enhancer in the food industry.

L-Tyrosine-CoA (L-Tyrosine-coenzyme A) is a derivative of coenzyme A.

Cholyl-L-tyrosine (TyrCA) is a bile acid conjugate of L-tyrosine and is efficiently hydrolyzed by pancreatic juice.

Stearyl tyrosine is an immunoadjuvants, long-chain stearyl ester of amino acids and peptides.

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.
