:L-Histidina
Descrição:
L-Histidina é um aminoácido essencial que desempenha um papel crucial em vários processos biológicos. É classificado como um aminoácido polar e carregado positivamente devido à presença de uma cadeia lateral de imidazol, que pode participar de ligações de hidrogênio e coordenação de íons metálicos. L-Histidina está envolvido na síntese de proteínas e é um precursor da histamina, um neurotransmissor vital. Tem um valor de pKa em torno de 6,0, indicando que pode atuar tanto como ácido quanto como base, tornando-o importante em sistemas de tamponamento dentro de fluidos biológicos. Este aminoácido também é conhecido por seu papel na catálise enzimática e é encontrado na hemoglobina, contribuindo para o transporte de oxigênio no sangue. L-Histidina é solúvel em água e tem um ponto de fusão relativamente alto. É comumente encontrado em fontes dietéticas como carne, peixe, produtos lácteos e certos grãos, tornando-o essencial para a saúde humana, particularmente no crescimento e na reparação de tecidos.

CAS:L-histidine is a molecule that chelates metal ions and inhibits their function. L-Histidine is used as an analytical reagent for the determination of metal ions in water, a polymerase chain reaction (PCR) inhibitor, and an immunosuppressant. L-histidine is also used to treat bowel disease and cancer by inhibiting the production of certain molecules. L-histidine has been shown to bind to toll-like receptor 4 (TLR4) in intestinal cells, which activates the immune system to produce cytokines such as IL-8. In addition, L-histidine can act as a cofactor for enzymes involved in protein synthesis by protecting them from oxidation. L histidine can also be found in the protein that binds with gold particles, forming colloidal goldFórmula:C6H9N3O2Cor e Forma:White PowderPeso molecular:155.15 g/molRef: 3D-FH15651
