P-nitrophenyl-A-L-arabinopyranoside

Description:
P-nitrophenyl-α-L-arabinopyranoside is a synthetic glycoside commonly used as a substrate in enzymatic assays, particularly for the detection of α-L-arabinofuranosidase activity. This compound features a p-nitrophenyl group, which serves as a chromogenic moiety, allowing for the quantification of enzymatic activity through colorimetric changes upon hydrolysis. The structure consists of an arabinopyranoside moiety linked to a p-nitrophenyl group, contributing to its solubility and reactivity. It is typically a white to yellow crystalline powder, soluble in water and organic solvents, making it versatile for laboratory applications. The compound is stable under standard laboratory conditions but should be stored away from light to prevent degradation. Its use in biochemical assays is significant for studying polysaccharide metabolism and enzyme kinetics, providing insights into carbohydrate-active enzymes. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
