H-Tyr-His-OH

Description:
H-Tyr-His-OH, also known as Tyr-His or Tyrosyl-Histidine, is a dipeptide composed of the amino acids tyrosine and histidine. It is characterized by the presence of a phenolic hydroxyl group from tyrosine, which contributes to its potential antioxidant properties. The histidine residue introduces an imidazole side chain, allowing for unique interactions in biological systems, such as metal ion coordination and proton transfer, which are crucial in enzymatic reactions. This dipeptide is soluble in water and exhibits a zwitterionic nature at physiological pH, making it relevant in various biochemical contexts, including peptide synthesis and drug development. H-Tyr-His-OH can also play a role in signaling pathways and may have implications in neurochemistry due to the involvement of its constituent amino acids in neurotransmitter systems. Its CAS number, 3788-44-1, allows for easy identification in chemical databases, facilitating research and application in fields such as biochemistry and pharmacology.
