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. WebWhen a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1. The carbon atom that forms the new chiral center (C-1) is called the anomeric carbon. Anomers are special cases …
