    摘要:Provided are hydrolases, including lipases, saturases, palmitases and/or stearatases, and polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. Further provided are polypeptides, e.g., enzymes, having a hydrolase activity, e.g., lipases, saturases, palmitases and/or stearatases and methods for preparing low saturate or low trans fat oils, such as low saturate or low trans fat animal or vegetable oils, e.g., soy or canola oils.

    摘要:Saturated triglycerides are reacted with glycerol in the presence of either a glycerolysis catalyst or a pre-formed glycerate to provide a product which is a mixture of monoglycerides, triglycerides, 1,2-diglycerides and 1,3-diglycerides. The mixture is stored in the presence of a low temperature rearrangement catalyst at a storage temperature below the melting point of the glyceride ester components of the mixture and substantially all of the mixture is converted into 1,3-diglycerides. In this way there are prepared, for example, 1-palmitoyl,3-stearoyl diglyceride, 1,3-distearoyl diglyceride and 1,3-dipalmitoyl diglyceride, which are appropriate precursors for the synthesis of confectioner's hard butters, and the like.

    参考标题:Regioisomeric Characterization Of Triacylglycerols Using Silver-Ion Hplc/ms And Randomization Synthesis Of Standards
    作者:Miroslav Lísa,Hana Velínská,Michal Holčapek |发布日期:2009.5.15
    摘要:Silver-Ion Normal-Phase High-Performance Liquid Chromatography (Hplc) Provides A Superior Separation Selectivity For Lipids Differing In The Number And Position Of Double Bonds In Fatty Acid Chains Including The Resolution Of Triacylglycerol (Tg) Regioisomers Under Optimized Conditions. Our Silver-Ion Hplc Method Is Based On The Coupling Of Three Columns In The Total Length Of 75 Cm And A New Mobile Phase Gradient Consisting Of Hexane−acetonitrile−2-Propanol Which Provides Better Resolution And Also Reproducibility In Comparison To Previously Used Mobile Phases. In Our Work, The Chemical Interesterification (Randomization) Of Single-Acid Tg Standards Is Used For The Generation Of Regioisomeric Series Of Tgs, Because It Provides A Random Distribution Of Fatty Acids In Tgs At Well-Defined Concentration Ratios. The Baseline Separation Of Regioisomeric Tg Pairs Containing Up To Three Double Bonds And The Partial Separation Of Tg Regioisomers With Four To Seven Double Bonds Are Reported For The First Time. Our Silver-Ion High-Performance Liquid Chromatography/mass Spectrometry (Hplc/ms) Method Is Applied For The Regioisomeric Characterization Of Complex Samples Of Plant Oils And Animal Fat, Where The Results Clearly Demonstrate Different Preference Of Sn-2 Occupation In Plants (Mainly Unsaturated Fatty Acids) Versus Animal Fat (Mainly Saturated Fatty Acids).
