CAS 71-00-1: L-Histidina
Descripción:
L-Histidina es un aminoácido esencial que desempeña un papel crucial en varios procesos biológicos. Se clasifica como un aminoácido polar y cargado positivamente debido a la presencia de una cadena lateral de imidazol, que puede participar en enlaces de hidrógeno y coordinación de iones metálicos. L-Histidina está involucrado en la síntesis de proteínas y es un precursor de la histamina, un neurotransmisor vital. Tiene un valor de pKa alrededor de 6.0, lo que indica que puede actuar como un ácido y una base, lo que lo hace importante en los sistemas de amortiguación dentro de los fluidos biológicos. Este aminoácido también es conocido por su papel en la catálisis enzimática y se encuentra en la hemoglobina, contribuyendo al transporte de oxígeno en la sangre. L-Histidina es soluble en agua y tiene un punto de fusión relativamente alto. Se encuentra comúnmente en fuentes dietéticas como carne, pescado, productos lácteos y ciertos granos, lo que lo hace esencial para la salud humana, particularmente en el crecimiento y la reparación de tejidos.

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:C6H9N3O2Forma y color:White PowderPeso molecular:155.15 g/molL-Histidine, Ph.
