:Ocratoxina A
Descripción:
Ocratoxina A es una micotoxina producida por ciertas especies de hongos, particularmente Aspergillus y Penicillium. Es un metabolito secundario que se encuentra comúnmente en varios productos agrícolas, incluidos granos, café y frutas secas. Químicamente, se clasifica como un compuesto fenólico y se caracteriza por su estructura, que incluye un grupo de fenilalanina unido a una unidad de 3-carboxi-4-hidroxi-2-piridona. Ocratoxina A es conocido por sus potenciales efectos nefrotóxicos, inmunotóxicos y carcinogénicos en humanos y animales, lo que lo convierte en una preocupación significativa en la seguridad alimentaria y la salud pública. Es estable bajo diversas condiciones ambientales, lo que contribuye a su persistencia en productos alimenticios contaminados. Las agencias reguladoras han establecido límites para Ocratoxina A en alimentos y piensos para mitigar los riesgos para la salud. Los métodos de detección suelen implicar técnicas avanzadas como la cromatografía líquida de alta eficacia (HPLC) acoplada con detección por fluorescencia, asegurando un monitoreo preciso de este contaminante dañino en los suministros de alimentos.

CAS:Producto controlado<p>Ochratoxin A is a mycotoxin that is found in cereals and cereal products. It can be detected by an analytical method that utilizes high performance liquid chromatography with fluorescence detection. Ochratoxin A has been implicated in the development of bowel diseases and has also been shown to inhibit catalase, peroxidase, and glucose-6-phosphate dehydrogenase activities. It also inhibits DNA polymerase, RNA polymerase, and mitochondrial enzymes involved in energy production. There is evidence that ochratoxin A may be genotoxic by inhibiting the repair of DNA damage caused by reactive oxygen species. The optimum concentration for ochratoxin A is between 0.1 and 1 micrograms per liter.br><br>Ochratoxin A is metabolized in plants via the phenylalanine pathway. This leads to increased levels of phenylalanine and p-hydroxybenzoic acid in the plant's tissues.br></p>Fórmula:C20H18ClNO6Pureza:(%) Min. 95%Forma y color:White PowderPeso molecular:403.81 g/molOchratoxin A
