4-METHYLUMBELLIFERYL OLEATE Chemical Properties,Usage,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
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
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.
