Lipids reactions

It is evident that all the described methods are based on reduction reactions. Substrates react either with long-living radicals (TEAC, TRAP), AOC (ORAC) or with the iron complex compound (FRAP), AOM concentration are obtained as a result of enzymatic reactions [51] or their existing level is registered with electron-spin resonance [52], Various modifications of peroxidation lipid reaction can also be applied [53],... [Pg.657]

Applications of whole-cell biocatalytic membrane reactors, in the agro-food industry and in pharmaceutical and biomedical treatments are listed by Giorno and Drioli [3], Frazeres and Cabral [9] have reviewed the most important applications of enzyme membrane reactors such as hydrolysis of macromolecules, biotransformation of lipids, reactions with cofactors, synthesis of peptides, optical resolution of amino acids. Another widespread application of the membrane bioreactor is the wastewater treatment will be discussed in a separate section. [Pg.312]

To make scVEGF-lipid conjugate, add mPEG-DSPE-maleimide directly to deprotection reaction to a final molar protein-to-lipidratio of 1 2. Residual DTT will not affect modification reaction. Incubate lipidation reaction mixture at room temperature for 1 h. [Pg.289]

For insertion into premade doxorubicin-loaded liposomes (Doxil), mix equal volumes of liposomes and lipidation reaction mixture and incubate at 37°C for 12-16 h (see Note 7). Purification of unreacted lipid and protein is not necessary at this step, because they do not interfere with insertion process and will be removed eventually by gel-filtration of decorated liposomes on Sepharose CL-4B. [Pg.289]

Reaction preferences in lipid oxidation have mostly been deduced from product analyses the few rate constants available for lipid reactions have been determined... [Pg.372]

Use of Enzymes Lipases are widely used in the processing of fats and oils as catalysts of a number of important lipid reactions, such as hydrolysis, esterification, and transesterification reactions (174). There are a wide number of lipases obtained from different sources, which are available commercially in their free/ crude or immobilized form. However, enzymes with a higher tolerance of pressure would be welcomed, and more research is needed to hopefully develop such enzymes (i.e., genetic engineering or marine sources of the deep ocean). [Pg.2825]

During 1-h lipidation reaction, equilibrate the Hu-column by passing through ten volumes of cold binding buffer. Dilute lipidation reaction mixture tenfold with cold binding buffer and load it on Hu-column at a slow rate, not exceeding... [Pg.263]

If one could conclusively show that there is an effect of plasticizers on reaction rate that is independent of moisture content or a , then this would demonstrate the significance of matrix properties for governing reaction rate. Labuza et al. (1977) studied the Maillard reaction and measured the effects of several parameters. These included temperature, reactant concentration, pH, buffers, and the addition of humectants. The formulation consisted of glucose and casein as reactants within a carrier matrix of microcrystalline cellulose and an inert lipid. Reaction rate was measured both as glucose loss, lysine loss, and pigment production (A42o). [Pg.358]

In biodiesel production, methanol and lipid reaction products are immiscible and form two phases at room conditions. This results in low reaction effidency and lipase deactivation. Hydrophobic solvents can minimize this effect, however, they are toxic and require a separation unit, which further increases the overall production cost Supercritical carbon dioxide (SC-COj) has frequently been used to replace organic solvents in various chemical processes. Due to its properties— including the easy and complete removal of the solvent, an ability to manipulate the physical properties of the solvent by simply changing the pressure or tanperature, nontoxidty, nonflammability, and enhancement of substrate mass transfer properties— it was suggested as a green solvent in biocatalyst reactions. A chemical feature of SC-COj is its low critical temperature (below the denaturation temperature of lipase). This feature combines the good solubility of nonpolar compounds, such as lipids, and makes SC-CO2 the perfect medium for biodiesel production. [Pg.136]
