General description

L-Tyrosine is an important amino acid mainly used as a dietary supplement.
L-tyrosine, an aromatic amino acid, is used common dietary supplement that has a wide range of applications in food and pharmaceutical industry. It is a precursor for preparing industrially important compounds such as 3,4-dihydroxy-L-phenylalanine (L-DOPA), melanin and p-hydroxystyrene. L-tyrosine can be synthesized by different biotechnological methods which are ecofriendly.

Other Notes

Amino acid precursor of dopamine and other catecholamines

The inflammasome adaptor ASC contributes to innate immunity through the activation of caspase-1. Here we found that signaling pathways dependent on the kinases Syk and Jnk were required for the activation of caspase-1 via the ASC-dependent inflammasomes NLRP3 and AIM2.

Low-grade gliomas (LGGs) may harbor malignant foci, which are characterized by increased tumor cellularity and angiogenesis. We used diffusion-weighted MR imaging (apparent diffusion coefficient [ADC]) and PET with the amino acid O-(2-(18)F-fluorethyl)-L-tyrosine ((18)F-FET) to search for focal changes of diffusion
