摘要

水溶性膳食纤维果胶是一种存在于陆生植物细胞壁中的多糖。它是由α -1,4键聚合而成的双半乳糖醛酸聚合物，侧链由13种不同的糖组成。由于其复杂的化学结构，果胶具有许多物理特性，包括胶凝特性和粘度，并在体内具有生理功能。果胶主链的酯化程度影响胶凝。此外，侧链结构已被证明影响果胶的抗肿瘤活性和调节肠道免疫等众所周知的生理功能，其中鼠李糖半乳糖醛酸- 1区尤为重要。本文综述了果胶分子结构与其功能之间的关系。不仅如此，我们还将讨论果胶仍然是一个神秘的功能，小肠绒毛形态变化的机制和生理意义。

Involvement of the Complex Polysaccharide Structure of Pectin in Regulation of Biological Functions

The water-soluble dietary fiber, pectin, is a polysaccharide present in the cell wall of terrestrial plants. It is a polymer of Dgalacturonic acid polymerized by alpha-1,4 linkages and has side chains composed of 13 different sugars. Due to its complex chemical structure, pectin has a number of physical characteristics, including gelling properties and viscosity, and has physiological functions in vivo. The degree of esterification of the pectin main chain affects gelling. In addition, the side chain structure has been shown to affect antitumor activity and regulation of intestinal immunity, which are well-known physiological functions of pectin, and the rhamnogalacturonan-I region is particularly important. This review discusses the correlations between the molecular structure of pectin and its functions. Not only that, we will discuss the mechanisms and physiological significance of small intestinal villus morphological changes, which is still a mysterious function of pectin.
