L-鼠李糖 是植物细胞壁多聚糖，鼠李糖醛酸I和鼠李糖醛酸的组分之一。它同样也存在于细菌细胞壁，是主要的抗原决定簇，导致致病性。L-鼠李糖 不能被人体吸收，但是能够被肠道菌群发酵。补充L-鼠李糖 能够减慢胃排空。L-鼠李糖 寡糖能和免疫原结合，用于癌症免疫治疗。摄入L-鼠李糖 能够提高血清丙酸盐水平。L-鼠李糖 一水合物用于： · 肺炎链球菌生物膜增强检测 · 人体肠道屏障通透性测试（作为糖类饮品） · 生成高效液相色谱（HPLC）标准曲线 L-Rhamnose is a part of plant cell wall polysaccharides, rhamnogalacturonan I and rhamnogalacturonan. It is also present in bacterial cell walland a major antigenic determinant contributing to its pathogenicity.L-rhamnose is non-absorbable in humans but is fermented by intestinal microbes. Supplementation of L-rhamnose slows down gastric emptying.L-rhamnose monosaccharide conjugated immunogens have applications in cancer immunotherapies. Intake of L-rhamnose elevates serum propionate levels
