4-Methylumbelliferyl β-D-galactopyranoside

Description:

4-Methylumbelliferyl β-D-galactopyranoside (MUG) is a synthetic compound commonly used as a substrate in biochemical assays, particularly for the detection of β-galactosidase activity. It is a glycoside, where the sugar moiety is β-D-galactopyranoside, linked to a 4-methylumbelliferone moiety. Upon hydrolysis by β-galactosidase, MUG releases 4-methylumbelliferone, which exhibits strong fluorescence, making it useful for quantitative analysis in various biological and environmental studies. MUG is typically a white to off-white crystalline powder, soluble in water and organic solvents, and is stable under normal laboratory conditions. Its fluorescence properties allow for sensitive detection, making it a valuable tool in microbiology, molecular biology, and enzymology. Additionally, MUG is often employed in assays to monitor microbial contamination in water and food products, as well as in research settings to study enzyme kinetics and regulation. Safety precautions should be taken when handling this compound, as with all chemical substances, to minimize exposure and ensure proper laboratory practices.
