Abstract：
Rhamnogalacturonan I (RG-I) belongs to the pectin family and is found in many plant cell wall types at different growth stages. It plays a significant role in cell wall and plant biomechanics and shows a gelling ability in solution. However, it has a significantly more complicated structure than smooth homogalacturonan (HG) and its variability due to plant source and physiological state contributes to the fact that RG-I\'s structure and function is still not so well known. Since functionality is a product of structure, we present a comprehensive review concerning the chemical structure and conformation of RG-I, its functions in plants and properties in solutions.
摘要：
鼠李糖半乳糖醛酸I（RG-I）属于果胶家族，存在于许多不同生长阶段的植物细胞壁类型中。它在细胞壁和植物生物力学中起着重要作用，并在溶液中显示出胶凝能力。然而,它的结构比光滑的同半乳糖醛酸（HG）明显更复杂，由于植物来源和生理状态，其变异性导致RG-I的结构和功能尚不为人所知。因为功能是结构的产物，我们对RG-I的化学结构和构象进行了全面的综述，它在植物中的功能和在溶液中的属性。
