浙大团队:鼠李半乳糖醛酸聚糖与饮食健康(综述)
  • I型鼠李半乳糖醛酸聚糖(RG-I)果胶的主链主要由→2)-α-L-鼠李糖-(1→4)-α-D-半乳糖醛酸-(1→重复单元组成,侧链含有半乳糖和阿拉伯糖;
  • 主要存在于柑橘、苹果、甜菜、土豆、秋葵、南瓜等果蔬及一些中草药的初级细胞壁中,不同来源的RG-I果胶结构差异较大;
  • 具有降血糖、降血脂、保护肠胃、调节免疫力、抗肿瘤、预防心脏疾病等潜在作用;
  • RG-I果胶在上消化道中几乎不被消化代谢,但可被肠道菌群发酵利用,发挥健康功效。

Abstract:收起
Rhamnogalacturonan I (RG-I) pectin is composed of backbone of repeating disaccharide units →2)-α-L-Rhap-(1→4)-α-D-GalpA-(1→ and neutral sugar side-chains mainly consisting of arabinose and galactose having variable types of linkages. However, since traditional pectin extraction methods damages the RG-I structure, the characteristics and health effects of RG-I remains unclear. Recently, many studies have focused on RG-I, which is often more active than the homogalacturonan (HG) portion of pectic polysaccharides. In food products, RG-I is common to fruits and vegetables and possesses many health benefits. This timely and comprehensive review describes the many different facets of RG-I, including its dietary sources, history, metabolism and potential functionalities, all of which have been compiled to establish a platform for taking full advantage of the functional value of RG-I pectin.
