o-Nitrofenil β-D-galactopiranósido

Descripción:

o-Nitrofenil β-D-galactopiranósido (ONPG) es un compuesto sintético comúnmente utilizado como sustrato en ensayos bioquímicos, particularmente para la detección de la actividad de β-galactosidasa. Es un glucósido, que consiste en una parte de galactopiranósido unida a un grupo o-nitrofenilo. Este compuesto es típicamente un polvo cristalino blanco a amarillo pálido que es soluble en agua y disolventes orgánicos. Tras la hidrólisis por β-galactosidasa, ONPG libera o-nitrofenol, que exhibe un color amarillo distintivo, lo que permite una fácil medición espectrofotométrica de la actividad enzimática. El compuesto es estable en condiciones normales de laboratorio, pero debe almacenarse en un lugar fresco y seco para prevenir la degradación. Sus aplicaciones se extienden más allá de los ensayos enzimáticos, ya que también puede servir como un sustrato modelo en estudios de metabolismo de carbohidratos y cinética enzimática. Se deben observar precauciones de seguridad al manejar ONPG, ya que puede representar riesgos para la salud si se ingiere o inhala.
