    克雷伯氏菌10型荚膜多糖的结构。
    摘要:
    发现来自10型克雷伯氏菌的荚膜多糖以3∶1∶1∶1∶1的比例含有D-半乳糖,D-葡萄糖,D-甘露糖和D-葡萄糖醛酸。多糖的酸水解得到一种醛糖二糖醛酸,一种醛糖三糖醛酸,一种醛糖四糖醛酸和两种中性二糖,其结构已确定。天然和羧基还原的多糖已经适当地进行了甲基化分析和史密斯降解。用碱基对甲基化多糖的降解建立了葡糖糖醛酸残基之前的糖单元的身份。糖残基的端基异构构型通过用三氧化铬氧化乙酰化的天然和羧基还原的多糖来确定。根据这些研究,

  • The synthesis of 2-, 3-, 4- and 6-O-α-d-glucopyranosyl-d-galactopyranose, and their evaluation as nutritional supplements for pre-term infants
    作者:Peter J. Meloncelli、Tracey M. Williams、Peter E. Hartmann、Robert V. Stick
    DOI:10.1016/j.carres.2007.04.022
    日期:2007.9
    Four methods have been screened for the synthesis of some alpha-D-glucopyrano sides, with the recently reported (Mukaiyama) combination of 2,3,4,6-tetra-O-benzyl- alpha-D-glucopyranosyl iodide and triphenylphosphine oxide being the most successful, especially in the diastereoselectivity exhibited. The alpha-D-glueopyranosides so obtained have been deprotected to yield 2-, 3-, 4- and 6-O-alpha-D-glucopyranosyl-D-galactopyranose. Only the last disaccharide showed any hydrolysis by alpha-glycosidases but this success was not emulated by mucosal extracts from the small intestine of the pig. (c) 2007 Elsevier Ltd.

  • Structure of the Klebsiella type 10 capsular polysaccharide
    作者:Arun K. Sarkar、Nirmolendu Roy
    DOI:10.1016/s0008-6215(00)90300-8
    日期:1986.9
    The capsular polysaccharide from Klebsiella Type 10 was found to contain D-galactose, D-glucose, D-mannose, and D-glucuronic acid in the ratios 3:1:1:1. Acid hydrolysis of the polysaccharide gave one aldobiouronic acid, one aldotriouronic acid, one aldotetraouronic acid, and two neutral disaccharides the structures of which were established. The native and carboxyl-reduced polysaccharide have been subjected
