4-Methylumbelliferyl oleate

Description:

4-Methylumbelliferyl oleate is a synthetic compound commonly used as a substrate in biochemical assays, particularly for the detection of lipase activity. It is an ester formed from oleic acid and 4-methylumbelliferone, a fluorescent compound. This substance is characterized by its ability to release 4-methylumbelliferone upon hydrolysis, which can be detected through fluorescence, making it a valuable tool in enzymatic studies. The compound is typically a pale yellow to light brown solid or oil, depending on its purity and form. It is soluble in organic solvents but has limited solubility in water. The fluorescence emitted upon enzymatic cleavage is often measured at specific wavelengths, allowing for quantitative analysis. Additionally, 4-Methylumbelliferyl oleate is utilized in various research applications, including studies on lipid metabolism and enzyme kinetics. Safety precautions should be observed when handling this compound, as with any chemical, to avoid potential hazards associated with its use.
