海藻多糖是一种天然的凝胶多糖,其分子链上原生的亲水、疏水基团赋予其天然的两亲性,能够在一定程度上改善非均相之间的界面相容性,具有天然凝胶网络结构的海藻多糖还可在溶胶体系中有效阻止分散相之间的再聚集,因而海藻多糖在乳化及分散中具有极佳的应用潜能。本文介绍了海藻酸盐、岩藻多糖、卡拉胶、琼脂、石莼多糖等常见海藻多糖的化学组成、结构与性质,并从其糖基单元上的羧基、硫酸酯基等亲水基团与甲氧基、乙酰基、蛋白质等疏水基团构成的两亲性结构出发,总结了两亲性结构对海藻多糖分子构型、表面活性及流变性质的影响,进而综述海藻多糖两亲性结构在乳化和分散中的应用。同时,还总结了通过物理或化学手段增强海藻多糖两亲性能的相关研究,例如带电疏水粒子的静电耦合、长碳链疏水化合物的化学接枝等,介绍了衍生化海藻多糖在乳化和分散中应用的研究进展,并对海藻多糖界面吸附活性增强的方向进行了展望。 相似文献

Artificially sulfated polysaccharides, as the mimetics of native heparin and heparan sulfate, are important bioactive compounds, since they show great potential for tuning crucial biological activities within living organisms. Herein, we summarize progress in the development of artificially sulfated polysaccharides, such as cellulose sulfate, chitosan sulfate, and other sulfated polysaccharides, with a particular focus on the fields of biomedical and bioengineering applications in the past ten years. Their effects on cell growth and differentiation, but also as building blocks for drug carriers and medical implants, are emphasized. 相似文献

Marine organisms have been recognized as a valuable source of bioactive compounds with industrial and nutraceutical potential. Recently, marine-derived carbohydrates, including polysaccharides and low molecular weight glycosylated oligosaccharides, have attracted much attention because of their numerous health benefits. Moreover, several studies have reported that marine carbohydrates exhibit various biological activities, including antioxidant, anti-infection, anticoagulant, anti-inflammatory, and anti-diabetic effects. The present review discusses the potential industrial applications of bioactive marine carbohydrates for health maintenance and disease prevention. Furthermore, the use of marine carbohydrates in food, cosmetics, agriculture, and environmental protection is discussed. 相似文献

Recent progress in controlled radical polymerizations, in particular atom transfer radical polymerization (ATRP), has provided a unique means for the design and synthesis of bioactive surfaces and functional biomaterials. This review summarizes such recent research activities. The synthesis strategies of bioactive surfaces and biomaterials via ATRP are described in detail. The highly robust and versatile ATRP technique is particularly suited for the preparation of functional bioactive surfaces, including antifouling, antibacterial, stimuli-responsive, biomolecule-coupled and micropatterned surfaces. In addition to bioactive surfaces, ATRP has also been widely used for the preparation of well-structured functional biomaterials, such as micellar delivery systems, hydrogels, cationic gene carriers and polymer–protein conjugates. The research activities in the last decade indicate that ATRP has become an essential tool for the design and synthesis of advanced, noble and novel biomaterials. 相似文献

Tangerine peel, a very abundant natural resource, only part of which has been used in traditional Chinese medicine and health foods but most were discarded as the waste, which should be fully utilized. Previous studies showed its functional components include volatiles, ?avonoids, phenolic acids, and pectin, all of which cannot be effectively extracted through traditional methods. A column chromatographic extraction with gradient elution was developed for one-step extraction of all bioactive substances from tangerine peel. Dried material was loaded into a column eluted with 2-fold of petroleum ether: ethanol (7:3, PE) for the volatiles fraction. Sequentially eluted with 4-fold of ethanol: water (5:5, EW) then separated into ?avonoids and polysaccharides by 80% ethanol precipitation of polysaccharides. The third eluted with 5-fold of water and then 60% ethanol precipitation of pectin. Through these procedures, volatiles, ?avonoids, and pectin in tangerine peel were simultaneously extracted at 98% extraction rates and simply separated at higher than 95% recovery rates. To further reduce solvent consumption and the volume of the final extract, cyclic column chromatographic extraction should be used. The method provides a simple and high ef?cient extraction and separation of a wide range bioactive substances. 相似文献
