    en.wikipedia.org/wiki/Tyrosine

    Tyrosine ball and stick model spinning. L-Tyrosine or tyrosine (symbol Tyr or Y) [2] or 4-hydroxyphenylalanine is one of the 20 standard amino acids that are used by cells to synthesize proteins. It is a conditionally essential amino acid with a polar side group.

  3. Thyroid hormones - Wikipedia

    en.wikipedia.org/wiki/Thyroid_hormones

    Thyroid hormones lead to heat generation in humans. However, the thyronamines function via some unknown mechanism to inhibit neuronal activity; this plays an important role in the hibernation cycles of mammals and the moulting behaviour of birds. One effect of administering the thyronamines is a severe drop in body temperature.

  4. Tyramine - Wikipedia

    en.wikipedia.org/wiki/Tyramine

    Tyramine (/ ˈ t aɪ r ə m iː n / TY-rə-meen) (also spelled tyramin), also known under several other names, [note 1] is a naturally occurring trace amine derived from the amino acid tyrosine. [4] Tyramine acts as a catecholamine releasing agent .

  6. Aromatic amino acid - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amino_acid

    In plants, the shikimate pathway first leads to the formation of chorismate, which is the precursor of phenylalanine, tyrosine, and tryptophan. These aromatic amino acids are the precursors of many secondary metabolites , all essential to a plant's biological functions, such as the hormones salicylate and auxin .

    Tyrosinase family related genes plays an important role in the evolution, genetics, and developmental biology of pigment cells, as well as to approach human disorders associated with defects in their synthesis, regulation or function in vertebrates three types of melanin producing pigment cells are well known since embryonic origin i.e., from ...

  8. Chymotrypsin - Wikipedia

    en.wikipedia.org/wiki/Chymotrypsin

    The main substrates of chymotrypsin are peptide bonds in which the amino acid N-terminal to the bond is a tryptophan, tyrosine, phenylalanine, or leucine. Like many proteases, chymotrypsin also hydrolyses amide bonds in vitro, a virtue that enabled the use of substrate analogs such as N-acetyl-L-phenylalanine p-nitrophenyl amide for enzyme assays.

  9. Tyrosine phosphorylation - Wikipedia

    Cartoon representation of the molecular structure of protein domain: p56 lck tyrosine kinase. Tyrosine phosphorylation is the addition of a phosphate (PO 4 3−) group to the amino acid tyrosine on a protein. It is one of the main types of protein phosphorylation. This transfer is made possible through enzymes called tyrosine kinases. Tyrosine ...
