Disruptions in the gut microbiota can impede gene expression and metabolic enzyme activity, thereby precipitating the onset of diverse ailments. polysaccharides, which are characterized by their high molecular weight and composed of multiple monosaccharides connected by glycosidic bonds, demonstrate notable biological activity. Gut microbiota possesses the ability to break down polysaccharides into butyrate, short-chain fatty acids, and other metabolites that can be readily absorbed and utilized by the human body. Furthermore, polysaccharides have the capacity to modulate the composition and metabolic products of the gut microbiota, thus fostering general well-being and averting the onset of diseases. This study reviews and summarizes the critically examines and consolidates the significant regulatory impacts of polysaccharides on gut microbiota, elucidating their structural attributes and potential mechanisms of operation. These findings offer a valuable point of reference for the subsequent advancement of prebiotic foods preparations based on polysaccharides.

基于螺旋藻多糖的益生元食品制剂——调节肠道微生物群和改善健康的一种有前景的方法


肠道微生物群的破坏会阻碍基因表达和代谢酶活性，从而加速多种疾病的发作。多糖具有分子量高、由多个单糖通过糖苷键连接而成的特点，具有显着的生物活性。肠道微生物群具有将多糖分解为丁酸盐、短链脂肪酸和其他易于被人体吸收和利用的代谢物的能力。此外，多糖具有调节肠道微生物群的组成和代谢产物的能力，从而促进整体健康并避免疾病的发作。本研究回顾并总结了多糖对肠道微生物群的显着调节影响，阐明了其结构属性和潜在的运作机制。这些研究结果为后续基于多糖的益生元食品制剂的进展提供了有价值的参考。
