From: Principles of Organic Chemistry, 2015 … WebAldohexoses have four chiral carbons and 2 4, or 16, stereoisomers—eight D forms and eight L forms (Figure 16.4). Some of the possible stereoisomers are much more common in nature than others, and most biochemical discussion centers on the common, nat-urally occurring sugars. For example, D sugars, rather than L sugars, predomi-nate in nature.
