lipases

Orlistat (Tetrahydrolipstatin) is a lipase inhibitor and a fatty acid synthase (FASN) inhibitor. Orlistat has been shown to promote weight loss.

Tributyrin (Glyceryl tributyrate), a neutral short-chain fatty acid triglyceride, is a stable and rapidly absorbed prodrug of Butyric Acid. It diffuses through biological membranes and is metabolized by intracellular lipases, releasing effective butyrate directly into cells in vivo, exhibiting potent proapoptotic, antiproliferative, and differentiation-inducing effects.

1,3-Didecanoylglycerol is a saturated diacylglycerol with decanoic acid (Item No. 20838) at the sn-1 and sn-3 positions. It has been used in the formation of lipid monolayers in the study of lipases.

AA26-9 is an effective and broad-spectrum inhibitor of serine hydrolase.

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.

2-Hydroxy arachidic acid methyl ester, a hydroxylated fatty acid methyl ester identified in sediment samples from the Harney River and in petroleum ether extracts of I. eriocarpa, serves as a volatile flavoring compound in anhydrous milk fat (AMF). Its presence is diminished upon treatment with lipases lipozyme-435 and TL-IM in a time-dependent fashion. [Matreya, LLC. Catalog No. 1710]

1-Palmitoyl-2-stearoyl-3-butyryl-rac-glycerol is a triacylglycerol that incorporates palmitic acid, stearic acid, and butyric acid at the sn-1, sn-2, and sn-3 positions, respectively. This compound serves as a substrate to establish the stereospecificity and typoselectivity of lipases.

4-Nitrophenyl butyrate is composed of a butyric acid chain esterified with a 4-nitrophenol group, giving it a yellow appearance. This compound is commonly used as a substrate in enzyme assays to measure the activity of esterases and lipases. When these enzymes cleave the ester bond, the nitrophenol group is released, changing the color from yellow to orange. The rate of this color change can be used to determine enzyme activity. Additionally, 4-Nitrophenyl butyrate serves as a reagent in organic synthesis and as an intermediate in dye production.

4-Nitrophenyl stearate is an ester formed from the condensation of stearic acid and 4-nitrophenol. It is commonly used as a substrate in enzymatic assays, where the hydrolysis of the ester bond by esterases and lipases can be monitored through absorbance or colorimetric changes. Additionally, 4-Nitrophenyl stearate serves as a model compound to study the enzymatic activity and selectivity of lipases and esterases from various sources. Its long hydrophobic tail enhances solubility in lipophilic environments, making it a valuable probe for researching lipid metabolism.
