| 摘 要： | 本文研究从锌酵母中分离出的酵母甘露多糖ＸＰ的特征和结构。ＸＰ经全水解和＾１３ＣＮＭＲ谱显示除甘露糖基外，还有少量Ｌ－鼠李糖基和甲氧基。甲基化分析、过碘酸盐氧化、Ｓｍｉｔｈ降解、乙酰解和部分酸水解显示ＸＰ的主链是１→６连接的甘露糖，侧链是１→２连接的甘露糖。＾１Ｈ及＾１３Ｃ ＮＭＲ谱表明所有糖苷键均为α型，结合元素分析ＸＰ基本是酵母甘露多糖和蛋白质以及锌的络合物。

| Abstract: | A yeast mannan XP from Zn-containing yeast was isolated and its characteristics and strueture were studied in detail. Completely hydrolyzed XP and the 13C NMR spectrum showed XP to contain a little L-rhemnose and O-methylated mannose besides mannose residues. Permethylation analysis, periodate oxidation,Smith degradation, acetolysis and partial acid bydrolysis revealed the main chains of XP as mannose of (1-6)-linkages and its side chains were mannose of (1-2)linkages. The 1H and 13C NMR spectrum indicated that all its glycosidic linkages are in the a-configuation. Elements analysis showed XP to be the complex of yeast mannan and protein and Zn. |
