  Chemoenzymatic synthesis of structured triacylglycerols by highly regioselective acylation

  摘要：

  A highly efficient two-step chemoenzymatic synthesis of structured triacylglycerols comprising a pure n-3 polyunsaturated fatty acid at the mid-position and a pure saturated fatty acid located at the end-positions is described. In the first step an immobilized Candida antarctica lipase was observed to display an excellent regioselectivity toward the end-positions of glycerol at 0-4degreesC using vinyl esters as acylating agents. The n-3 fatty acids were introduced into the remaining mid-position highly efficient and in excellent yields using EDCI coupling agent. (C) 2003 Elsevier Ltd. All rights reserved.

  AbstractSeveral triacylglycerols (TAG) that contained eicosapentaenoic acid (EPA) were chemically synthesized and stored at 25°C to assess the influence of TAG structure on oxidative stability and formation of oxidation products. Oxidative stability was evaluated by oxygen consumption during storage of the TAG. Autoxidation products of TAG were analyzed by high‐performance liquid chromatography (HPLC) and liquid chromatography‐mass spectrometry (LC‐MS). Results showed that a 2:1 (mole/mole) mixture of trieicosapentaenoylglycerol (EEE) and tripalmitoylglycerol (PPP) was most susceptible to autoxidation. The oxidative stability of TAG that contained EPA and palmitic acid was negatively correlated with the moles of EPA in a single TAG molecule. When TAG with one EPA and two other fatty acids were oxidized, chainlength of constituent fatty acids hardly affected the oxidative stability of EPA‐containing TAG molecules, except for stearic acid. HPLC and LC‐MS analyses showed that monohydroperoxides were major oxidation products regardless of type of TAG. Bis‐ and tris‐hydroperoxides were formed during autoxidation of EEE and dieicos‐apentaenoylpalmitoylglycerol. Monohydroperoxy epidioxides were found in all autoxidized TAG. These observations suggested that TAG structure affected the oxidation of TAG with highly unsaturated fatty acids.
