Figure 1.Structure ofl-ascorbic acid. l-AA has chiral centers at carbons 4 and 5 and can exist in four stereoisomeric forms.Enantiomericpairs arel- andd-AA andl- andd-araboascorbic acid.l-AA andd-araboascorbic acid (more commonly known asd-isoascorbic acid), or erythorbic acid, areepime...
Although the chemical properties of D-ascorbic acid is same with L-ascorbic acid, it shares a different structure, that makes it impossible for D-ascorbic acid to be synthesized by your body and cannot be used as a vitamin supplement. Thus, it has no biological activity. ...
