Glucose an aldohexose, exists as D and L forms. The furthest asymmetric carbon from the aldehyde group is C-5. D-glucose is called D because the configuration of the atoms bonded to C-5 is the same as for D-gly- ceraldehyde. Similarly D-fructose﹙a ketohexose﹚ is designated D because the configuration
环状结构：醛基或酮基跟一个羟基反应共价闭合，形式上一个糖的醛基和羟基反应生成了一个半缩醛，而一个酮基与一个羟基反应生成一个半缩酮，在同一分子内这个反应能进行，单糖的开链式形成了糖环，葡萄糖环形成一个六碳环。
