WebJan 3, 2015 · One example of a chiral molecule is glucose, that naturally only occurs in the so-called right-hand variety, called D-glucose or dextrose (dexter=Latin for right). It is possible to make L-glucose (its mirror-image) by chemical synthesis. The human body cannot use L-glucose. It tasts just as sweet, but no calories can be gained from it. WebClassification Aldohexoses. The aldohexoses are a subclass of the hexoses which, in the linear form, have the carbonyl at carbon 1, forming an aldehyde derivative with structure H–C(=O)–(CHOH) 5 –H. The most important example is glucose.. In linear form, an aldohexose has four chiral centres, which give 16 possible aldohexose stereoisomers (2 …
