pyranose

1.LCP-Ⅴ is likely to be a glycoprotein for a few protein in its structure, the IR analyse result indicated that its monosaccharide can be a pyranose, and there are few mannoside linkage.

IR谱图分析表明LCP-Ⅴ的组成单糖为吡喃糖，且其结构中可有少量甘露糖苷键；

2.Glucose cyclizes to form asix- membered pyranose ring whilst five –carbon surgars and six-carbon ketose sugars (ketohexoses) such as fructnose rings.
