    Elucidation of Structural Isomers from the Homogeneous Rhodium-Catalyzed Isomerization of Vegetable Oils
    摘要:
    The structural isomers formed by the homogeneous rhodium-catalyzed isomerization of several vegetable oils have been elucidated. A detailed study of the isomerization of the model compound methyl linoleate has been performed to correlate the distribution of conjugated isomers, the reaction kinetics, and the mechanism of the reaction. It has been shown that [RhCl(C8H8)(2)](2) is a highly efficient and selective isomerization catalyst for the production of highly conjugated vegetable oils with a high conjugated linoleic acid (CLA) content, which is highly desirable in the food industry. The combined fraction of the two major CLA isomers [(9Z, 11E)-CLA and (10E, 12Z)-CLA] in the overall CLA mixture is in the range from 76.2% to 93.4%. The high efficiency and selectivity of this isomerization method along with the straightforward purification process render this approach highly promising for the preparation of conjugated oils and CLA. Proposed improvements in catalyst recovery and reusability will only make this method more appealing to the food, paint, coating, and polymer industries in the future.

    This study aimed to assess the oral absorption and plasma kinetics of two main isomers contained in commercial conjugated linoleic acid (CLA)-rich oil (Tonalin TG-80), rumenic acid (RA), and C18:2 trans-10, cis-12. The isomer plasma disposition after the single oral dose of 3000 mg of Tonalin TG-80/kg, containing 1200 mg/kg of each isomer, was studied in rats. The isomer plasma concentrations were

    (i.e., cis and trans). In this study, CID performed on proton-bound complexes of fatty acid methyl esters and iodoaniline (and related reagents) reveals unusual fragmentation patterns. CID products are shown to result from proton transfer and are associated with specific structures of the unsaturated lipids. Notably, CID of these complexes can not only distinguish cis- and trans-fatty acid methyl esters
    不饱和脂质中的双键位置和立体化学会对生物学特性和活性产生深远的影响,但通过质谱法确定这些特征通常具有挑战性。脂质鉴定的传统技术依赖于碰撞诱导解离 (CID),并且通常无法区分脂质异构体,尤其是那些涉及双键位置和几何形状(即顺式和反式)的异构体。在这项研究中,对脂肪酸甲酯和苯胺(及相关试剂)的质子结合复合物进行的 CID 揭示了不寻常的碎片模式。CID 产物被证明是由质子转移产生的,并且与不饱和脂质的特定结构有关。值得注意的是,这些复合物的 CID 不仅可以区分顺式和反式脂肪酸甲酯,但也区分共轭双键排列与非共轭类似物。在此,通过稳定同位素标记研究了支持这种独特 CID 行为的机制,并建议涉及卡宾和自由基中间体。

    A process for producing industrially important chemicals from renewable resources is disclosed. This “biobased” process employs readily available, renewable resources comprising fatty acids rather than exploiting fossil sources, such as coal and petroleum. In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.

    The present invention provides compositions and methods for the delivery of interfering RNAs such as siRNAs that silence APOB expression in cells such as liver cells. In particular, the nucleic acid-lipid particles provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells such as liver cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of APOB at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.
