Evidence from determinations of crystal structure relating to the shortening of carbon-oxygen bonds in the anomeric position in pyranose sugars is presented. There is a high degree of probability that the C(1)-O(1) bond is shortened by about 0.04 A relative to the other C-O single-bond lengths, except in the case of an axially oriented glycosidic group where there is evidence of a distinction between the two ring C-O bonds.
本文给出了关于吡喃糖中异头碳位置碳-氧键缩短的晶体结构测定证据。相对于其他碳-氧单键长度，C(1)-O(1)键很有可能缩短约0.04埃，轴向取向糖苷基团的情况除外，在该情况下两个环碳-氧键存在差异的证据。
