摘要:

近年来对珍珠层中蛋白质及蛋白质对碳酸钙结晶控制作用的研究得出珍珠层中含各种各样的功能蛋白质,不同种类动物形成的珍珠层中所含的主要蛋白质种类不同,它们各自独有自已的结构和功能。蛋白质对珍珠层中无机相的成核、结晶、形貌等的控制作用明显存在,但是,目前体外的仿生矿化实验不能复制珍珠层中无机相的形貌,这种控制作用的详细机理仍不清楚,人们对其认识还处于初步的阶段。

Abstract:

The published researches on proteins in nacre and the control of nucleantion of calcium carbonate by the nacre proteins obtain lots achievements recently. There are many different functional proteins found in nacre. The key proteins in function and structure are different in the nacres from different animals. The control of nucleation, growth, morphology of calcium carbonate in nacre by the proteins are obvious, but the biomimetic mineralization in vitro could not reproduce inorganic phase morphology of nacre nowadays. The control mechanism of calcium carbonate by proteins in nacre is still not clear.
