Abstract

Hydrogels made from natural polymers have excellent application potential due to their good biocompatibility. However, it is difficult to maximise the benefits of hydrogels when the gel network is formed by a single substance. The purpose of this study was to investigate the relationship between the interaction of modified soybean lipophilic proteins (SLP) and lysozyme (LY) and the formation of heteroprotein complexes. Subsequently, interpenetrating network (IPN) hydrogels were further synthesized on the basis of heteroprotein (HP) complexes and sugar beet pectin (SBP) as the backbone. The strong interaction between SLP and LY drove them to spontaneously form heteroprotein complexes. The HP-SBP IPN imparted good mechanical properties to the hydrogel, which could withstand a maximum pressure of 7500 pa at 88 % strain. Meanwhile, there was still 93.52 % of water being trapped in IPN after freeze-thawing. The HP-SBP IPN hydrogels could effectively protect the encapsulated substance during UV irradiation and maintain its morphology after undergoing dynamic pH changes. Furthermore, the HP-SBP IPN hydrogels could regulate their release ability through their own swelling and achieved more than 88 % release rate in simulated intestinal fluid. Therefore, this study was expected to provide a potential strategy for the synthesis of IPN hydrogels.

基于甜菜果胶和杂蛋白复合物的互穿网络水凝胶的合成与表征：结构特征与理化性质

天然聚合物制成的水凝胶具有良好的生物相容性，因此具有极佳的应用潜力。然而，当凝胶网络由单一物质形成时，很难最大限度地发挥水凝胶的优势。本研究旨在探讨改性大豆亲脂性蛋白（SLP）和溶菌酶（LY）的相互作用与异种蛋白复合物形成之间的关系。随后，以异性蛋白（HP）复合物为基础，甜菜果胶（SBP）为骨架，进一步合成了互穿网络（IPN）水凝胶。SLP 和 LY 之间的强相互作用促使它们自发形成异种蛋白复合物。HP-SBP IPN 为水凝胶带来了良好的机械性能，在应变为 88% 的情况下可承受 7500 pa 的最大压力。同时，冻融后仍有 93.52% 的水分滞留在 IPN 中。HP-SBP IPN 水凝胶能在紫外线照射下有效保护封装物质，并在经历动态 pH 值变化后保持其形态。此外，HP-SBP IPN 水凝胶还能通过自身溶胀调节释放能力，在模拟肠液中的释放率超过 88%。因此，这项研究有望为 IPN 水凝胶的合成提供一种潜在的策略。

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
