    Transglutaminase Catalyzed Reactions: Impact on Food Applications

    JOURNAL OF FOOD SCIENCE, Issue 8 2002
    G.A.H. DeJong
    ABSTRACT: Transglutaminases can perform various reactions that are based on cross-linking, acyl-transfer and deamidation. These enzymes are found in many different organisms where they have very specific roles. The basic reaction mechanism of these transglutaminases is similar. The reactions catalyzed by transglutaminases have proven to be useful in production of different kinds of protein ingredients and food products. In this review, we will show important aspects of transglutaminase cross-linking in respect to substrate specificity, accessibility of proteins, regulation and differences in reactions and safety. These aspects will be viewed in respect to food applications [source]

    Asymmetric Amplification in Phosphoric Acid Catalyzed Reactions,

    ANGEWANDTE CHEMIE, Issue 36 2010
    Nan Li
    Mehree! Die asymmetrische Verstärkung in Phosphorsäure-Katalysen folgt aus der Bildung schlechter löslicher, supramolekularer Strukturen (siehe Schema; O,rot, P,gelb, C,grau, H,weiß) aus den racemischen Phosphorsäuren, die darin Wasserstoffbrücken mit Kristallwasser-Molekülen bilden. Dieses Ergebnis erklärt, warum auch bei Einsatz nicht enantiomerenreiner Phosphorsäuren hoch enantioselektive Reaktionen gelingen können. [source]

    Building Addressable Libraries: Site-Selective Lewis Acid (Scandium(III)) Catalyzed Reactions,

    Gezielt verankert: Mikroelektroden-Arrays mit 1024 oder 12,544 Elektroden pro cm2 wurden für ortsselektive Lewis-Säure-katalysierte Reaktionen eingesetzt. Eine an den Elektroden erzeugte ScIII -Spezies fungiert als die Lewis-Säure, und das Reagens wird mithilfe eines Reduktionsmittels an die Elektroden fixiert. Die Strategie ließ sich auf eine Mehrkomponentensynthese von Tetrahydropyran (siehe Schema), eine Diels-Alder-Reaktion und eine Veresterung anwenden. [source]

    Consideration of the Effect of Irregular Catalytic Active Component Distributions in Mesopores , Extension of a Model for Wall Catalyzed Reactions in Microchannel Reactors

    CHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 7 2003
    B. Platzer
    Abstract Data available from the literature and experimental results have shown that the distribution of the catalytic active components can be irregular already for fresh catalysts. The determination of the local concentrations of the catalytic active components using wavelength dispersive X-ray spectroscopy confirms this for microstructured wafers used in microchannel reactors. Considering this nonuniform distribution, the used model gives the relation between the local concentration profiles of the reactants inside the pores and the product yield in the entire pore. These results were used in an equation for the diffusion flux at the pore mouth, which is useful for a microchannel model developed in a recent paper [1]. The theoretical considerations deal with cylindrical pores with known reactant concentrations at the pore mouth and known distribution of the catalytic active component within the pore. Beside numerical results, some analytical solutions with low mathematical expense, applicable to special cases, are discussed. The nonconsideration of the irregular distribution of the catalytic active component can be the reason for difficulties during the extrapolation of experimental results to slightly different conditions and can have a great influence on the reaction results. The regarded examples are typical of wall-catalyzed reactions in microchannel reactors with mesopores. [source]
