Nettet13. apr. 2024 · The consequence of the massive increase in population in recent years is the enormous production of mainly industrial waste. The effort to minimize these waste products is, therefore, no longer sufficient. Biotechnologists, therefore, started looking for ways to not only reuse these waste products, but also to valorise them. This work … NettetLipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules. Initial lipase digestion occurs in the lumen (interior) of the small intestine. Bile salts reduce the surface tension of the fat droplets so that the lipases can attack the triglyceride molecules.

Lingual lipase uses a catalytic triad consisting of aspartic acid-203 (Asp), histidine-257 (His), and serine-144 (Ser), to initiate the hydrolysis of a triglyceride into a diacylglyceride and a free fatty acid. First, there is a series of deprotonations that make the serine a better nucleophile. The lone pair on the oxygen of the serine then undergoes a nucleophilic addition to either the first o… NettetThis lipase hydrolyzes dietary triglycerides to mainly diglycerides and free fatty acids and may serve as a complement to the poorly developed pancreatic lipase activity. Furthermore, by the formation of polar lipolytic products the digestibility of dietary lipids in the duodenum may increase. Human milk lipase contributes to the lipolysis.

NettetHuman lipase purified from lingual serous glands or gastric juice has a MW of 45k to 51K but tends to aggregate (MW 270-300K and 500K) and is highly hydrophobic. Secretion of gastric lipase appears to be stimulated by at least two receptor mechanisms. NettetLipase-catalyzed transesterification and esterification reactions were reported that could proceed with a two-substrate reaction model, ping-pong bi–bi and order bi–bi mechanism [13,28]. In contrast, there are limited data available on the packed-bed bioreactors for continuous synthesis of DHA and EPA ethyl esters.
