Extraction of Functional Lipids from <i>Nannochloropsis </i>sp.

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

Extraction and Enzymatic Modification of Functional Lipids from Soybean Oil Deodorizer Distillate

Crude vegetable oils contain triacylglycerols as major component and various minor components such as diacylglycerols, monoacylglycerols, free fatty acids, phospholipids, tocopherols, sterols, squalene, color pigments, waxes, aldehydes, ketones, triterpene alcohols and metals that may affect the quality of the final product. The minor components are removed partially or entirely by either physi...

Improved Procedure for the Extraction of Lipids from Human Erythrocytes.

Extraction of Lipids from Fermentation Biomass Using Near-critical Dimethylether

The extraction of lipids from both wet and dry biomass produced by fermentation has been carried out using near-critical dimethylether (DME) as the extraction solvent. Fermentations were carried out from a shake flask to 300 litre scale using the micro-organism Mortierella alpina, and up to a 20 litre scale for Phaffia rhodozyma and Agrobacterium tumefaciens. The lipids extracted at a laborator...

Extraction of Lipids from Phospholipid Membranes by Steered Molecular Dynamics

Steered molecular dynamics (SMD) simulations were employed to investigate the extraction step of the lipid head group cleavage reaction by human synovial phospholipase A2 (PLA2) by pulling a lipid molecule from a monolayer of dilauroyl-phosphatidyl-ethanolamin lipids into the active site of PLA2 and into the aqueous phase. The results of the simulations were compared to draw inferences about th...
