4-Methylumbelliferyl oleate Chemical Properties, Uses, Production
Description
4-Methylumbelliferyl (4-MU) oleate is a fluorogenic substrate for acid and alkaline lipases. It is cleaved by lipases, liberating 4-MU, which has an emission maximum at 445-454 nm. The excitation maximum for 4-MU is pH-dependent: 330, 370, and 385 nm at pH 4.6, 7.4, and 10.4, respectively.
Chemical Properties
Colourless Oil
Uses
4-Methylumbelliferyl oleate can act as Fatty acyl esters for use as fluorogenic substrates to continuously follow the hydrolytic activity of carboxylesterases, such as acid and alkaline lipases.
Uses
Fluorogenic substrate for lipases.
Uses
4-Methylumbelliferyl oleate has been used:
- as a substrate to assay the activity of non-specific esterases
- to determine lipase activity
- as a substrate to evaluate pancreatic lipase inhibitory activity
