Inhibition of lipases by -polylysine
Oral administration of -polylysine to rats reduced the peak plasma triacylglycerol concentration. In vitro, -polylysine and polylysine strongly inhibited the hydrolysis, by either pancreatic lipase or carboxylester lipase, of trioleoylglycerol (TO) emulsified with phosphatidylcholine (PC) and taurocholate. The -polylysine concentration required for complete inhibition of pancreatic lipase, 10 g...
متن کاملStereoselectivity of lipases. II. Stereoselective hydrolysis of triglycerides by gastric and pancreatic lipases.
In the present study, porcine pancreatic lipase, rabbit gastric lipase, and human gastric lipase stereospecificity toward chemically alike, but sterically nonequivalent ester groups within one single triglyceride molecule was investigated. Lipolysis reactions were carried out on synthetic trioctanoin or triolein, which are homogenous, prochiral triglycerides, chosen as models for physiological ...
متن کاملEstolides Synthesis Catalyzed by Immobilized Lipases
Estolides are vegetable-oil-based lubricants obtained from oleic acid or any source of hydroxy fatty acids. In this work, the estolides synthesis from oleic acid and methyl ricinoleate (biodiesel from castor oil), using immobilized commercial lipases (Novozym 435, Lipozyme RM-IM, and Lipozyme TL-IM) in a solvent-free medium was investigated. Acid value was used to monitor the reaction progress ...
متن کاملSecretion of Extracellular Lipases by Cundidu ZipoZyticu
Lipolytic activity was associated with Candida lipolytica in several early studies (Long, 1936; Long & Hammer, 1938, 1939), and the influence of culture conditions on lipase production has been described by Peters & Nelson (1948). Studies on the intracellular lipases (Lloyd et al., 1971) indicated that C. lipoiytica grown in liquid media with glucose as a carbon source contained five distinct l...
متن کاملInhibition of microbial lipases by fatty acids.
Addition of lard or sodium oleate to the medium used for lipase production by Pseudomonas fragi resulted in a decreased accumulation of lipase in the culture supernatant fluid without affecting cell growth. The production and activity of lipase was inhibited by lard, sodium oleate, and the salts of other unsaturated fatty acids. Some divalent cations, Tweens, lecithin, and bovine serum prevente...
