The authors have devised the methods for preparing free hyaluronic acid (HA) and non-aggregating fraction of protein-chondroitin-keratan sulfate (PCKS), as well as those for preparing their Na+, K+, Ca2+ and Mg2+ salts (acid and neutral). Infrared spectroscopy has demonstrated the presence of intermolecular hydrogen bonds, formed by hydroxyl groups, in HA and PCKS macrocomplexes and in PCKS acid salts. HA salts appeared not to form macrocomplexes at the expense of intermolecular hydrogen bonds.
作者们已经设计出了制备游离透明质酸（HA）和蛋白质-硫酸软骨素-硫酸角质素（PCKS）非聚集部分的方法，以及制备它们的Na+、K+、Ca2+和Mg2+盐（酸性和中性）的方法。红外光谱表明，在HA和PCKS大分子复合物以及PCKS酸盐中存在由羟基形成的分子间氢键。HA盐似乎不会以分子间氢键为代价形成大分子复合物。
