p-Nitrophenyl β-D-lactoside

Description:

p-Nitrophenyl β-D-lactoside is a synthetic compound commonly used as a substrate in biochemical assays, particularly for the study of β-galactosidase activity. It is characterized by its structure, which includes a p-nitrophenyl group attached to a β-D-lactose moiety. This compound is typically a white to pale yellow crystalline solid, soluble in water and organic solvents like methanol and ethanol. Upon hydrolysis by β-galactosidase, it releases p-nitrophenol, which can be quantified spectrophotometrically, making it a valuable tool in enzymatic studies. The presence of the nitrophenyl group imparts a distinct yellow color to the solution, facilitating easy detection and measurement. p-Nitrophenyl β-D-lactoside is also utilized in various research applications, including studies on lactose metabolism and enzyme kinetics. As with many chemical substances, proper handling and safety precautions should be observed, as it may pose health risks if ingested or inhaled.
