<p>4-Methylumbelliferyl nonanoate is a fluorogenic substrate for lipase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl nonanoateas a substrate for measuring the lipase activity is used for the detection of lipase deficiency that could lead to pancreatic insufficiency.</p>

<p>4-Trifluoromethylumbelliferyl β-D-galactopyranoside is a fluorogenic substrate for beta-galactosidase&Tab;. Upon hydrolysis, the fluorogenic moiety (blueish) 4-trifluoromethylumbelliferone (also known as TFMU) is released. 4-Trifluoromethylumbelliferyl β-D-galactopyranoside is commonly used in bacterial detection and in LacZ gene expression assays.</p>
