糖类物质和无机盐之间的分子-离子相互作用无论是在生物物理学还是在生物化学方面都有很重要的意义.本文利用粉末X射线衍射法(PXRD)来考察β-环糊精(β-CD)与一系列无机盐加合物之间的分子-离子相互作用.结果显示,同系无机盐与β-CD加合物的PXRD谱之间存在着微妙的差异性.这些PXRD谱主要反映β-CD的堆积方式,因此,它们的差异性揭示了分子-离子相互作用的多样性与复杂性.造成PXRD谱差异性的影响因素包括制备条件、阴离子和阳离子的性质、离子电荷等.由糖和盐之间的分子-离子相互作用所诱导的结晶行为多样性将为碳水化合物在生物物理、分子生物学、临床医学、纳米科学与技术等方面的学术与应用研究提供重要的启示.
Molecular-ionic interactions between carbohydrates and inorganic salts are of great importance both in biophysics and in biochemistry.In this paper, powder X-ray diffraction (PXRD) β-CD) with a series of inorganic salt adducts, the results show that there is a subtle difference between the PXRD spectra of homologous inorganic salts and β-CD adducts.These PXRD spectra are mainly Therefore, their differences reveal the diversity and complexity of molecular-ionic interactions.The influencing factors of PXRD spectrum include the preparation conditions, the properties of anions and cations, ionic charges and the like. The crystallization behavior diversity induced by the molecular-ionic interaction between sugar and salt will provide important insights into the academic and applied research of carbohydrates in biophysics, molecular biology, clinical medicine, nanoscience and technology.
