4-Nitrophenyl palmitate serves as a colorimetric substrate for lipase and esterase, enabling the quantification of enzyme activity through the release and colorimetric detection of 4-nitrophenol at 410 nm following enzymatic hydrolysis. This compound facilitates the characterization of enzyme activity across diverse bacterial and mammalian sources, including Burkholderia and porcine pancreatic lipases.
1-Stearoyl-2-lauroyl-rac-glycerol, a diacylglycerol, features stearic acid at the sn-1 position and lauric acid at the sn-2 position. It serves as a substrate for the rat diacylglycerol lipase DDHD2.1.
