Structural investigations of the regio- and enantioselectivity of lipases [PDF]

, 1998
Although lipases are widely applied for the stereospecific resolution of racemic mixtures of esters, the atomic details of the factors that are responsible for their stereospecificity are largely obscure. We determined the X-ray structures of Pseudomonas

Aqueous Two-Phase Systems for the Isolation and Partial Purification of Lipases from Soil Bacteria [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2020
Aqueous Two-Phase System (ATPS) is an effective, simple, and single-step technique used for the partial purification of biological molecules. The aim of the study was to develop ATPS technique for the isolation and partial purification of lipases.

Lipase and Its Unique Selectivity: A Mini-Review

Journal of Chemistry, 2022
Contrary to other solid catalysts, enzymes facilitate more sophisticated chemical reactions because most enzymes specifically interact with substrates and release selective products. Lipases (triacylglycerol hydrolase, EC 3.1.1.3), which can catalyze the

Post-Synthetic Enzymatic and Chemical Modifications for Novel Sustainable Polyesters

Frontiers in Bioengineering and Biotechnology, 2022
Because of their biodegradability, compostability, compatibility and flexible structures, biodegradable polymers such as polyhydroxyalkanoates (PHA) are an important class of biopolymers with various industrial and biological uses. PHAs are thermoplastic

Lipases: it's not just pancreatic lipase!

American Journal of Veterinary Research, 2022
ABSTRACT Lipases are water-soluble enzymes that hydrolyze water-insoluble lipid molecules, such as triglycerides, phospholipids, and galactolipids. They are ubiquitous in nature and are present in humans, animals, insects, plants, fungi, and microorganisms.

Hepatic Lipase

Journal of Atherosclerosis and Thrombosis, 1998
Hepatic lipase (HL) is an important enzyme that is involved in the metabolism of chylomicrons, intermediate density lipoproteins, and high density lipoproteins. HL may affect the liver uptake of remnant lipoproteins by modifying their compositions.
