Abstract
The vacuum ultraviolet CD of keratan sulfate reveals an intense negative CD band at 171 nm. Its intensity can be rationalized with a recently proposed quadrant rule in terms of the acetamido group being slightly tilted toward the hexosaminidic linkage oxygen. The same structural feature accounts for the particularly intense negative n-pi CD band near 210 nm.
摘要
硫酸角质素的真空紫外圆二色光谱在171纳米处显示出一个强烈的负圆二色带。根据最近提出的象限规则，其强度可以通过乙酰氨基稍微向己糖胺键氧倾斜来解释。相同的结构特征解释了在210纳米附近特别强烈的负n-π圆二色带。
