o-Nitrofenil β-D-galattopiranoside

Descrizione:

o-Nitrofenil β-D-galattopiranoside (ONPG) è un composto sintetico comunemente utilizzato come substrato in saggi biochimici, in particolare per la rilevazione dell'attività della β-galattosidasi. È un glicoside, composto da una parte di galattopiranosio legata a un gruppo o-nitrofenile. Questo composto è tipicamente una polvere cristallina bianca a giallo pallido, solubile in acqua e solventi organici. Dopo l'idrolisi da parte della β-galattosidasi, l'ONPG rilascia o-nitrofenolo, che presenta un colore giallo distintivo, consentendo una facile misurazione spettrofotometrica dell'attività enzimatica. Il composto è stabile in condizioni normali di laboratorio, ma deve essere conservato in un luogo fresco e asciutto per prevenire la degradazione. Le sue applicazioni si estendono oltre i saggi enzimatici, poiché può anche fungere da substrato modello negli studi sul metabolismo dei carboidrati e sulla cinetica enzimatica. Devono essere osservate precauzioni di sicurezza quando si maneggia l'ONPG, poiché può comportare rischi per la salute se ingerito o inalato.
