木糖在哺乳动物体内功能的研究

Study on the function of xylose in mammals

木糖(xylose)是自然界中仅次于葡萄糖的第二大糖类物质,作为五碳醛糖,木糖多以缩聚化合物形式组成半纤维素等。尽管针对植物和微生物中木糖的代谢与结构的相关研究众多,但是在动物尤其哺乳动物中的研究较少。本综述总结了哺乳动物体内木糖的吸收、来源与利用,参与的糖链结构,及木糖相关结合蛋白的相关研究,为阐明木糖在哺乳动物体内的重要作用及其潜在的功能研究提供参考。

Xylose is the second largest carbohydrate in nature after glucose.As a pentaaldehyde,xylose exists mostly as hemicellulose in the form of polycondensation compounds.Although there are many studies related to the metabolism and structure of xylose in plants and microorganisms,there are fewer studies in animals,especially mammals.This review summarized the absorption,source and utilization of xylose in mammals,participates in sugar chain structure,and related research on xylose-related binding proteins,provided a theoretical summary for elucidating the important role of xylose in mammals,and provided potential references for its functional studies.
