WebFeb 5, 2011 · Because of chirality, lactic acid has two optical isomers: L-(+)-lactic acid or (S)-lactic acid and D-(−)-lactic acid or (R)-lactic acid. L-lactic acid is the natural and biologically important isomer, but D-form can be produced by microorganisms or by racemization. Stereoisomers of lactic acid are shown in Fig. 1.

WebMay 4, 2009 · Fisher developed the D / L system as a means to describe carbohydrate stereoisomers ( Fischer, 1891 ). It is also commonly applied to amino acids. “ D ” or “ L ” is assigned by relating a molecule to (chiral) glyceraldehyde. The molecule is written in a Fisher projection. The R / S system is an important nomenclature system for denoting enantiomers. This approach labels each chiral center R or S according to a system by which its substituents are each assigned a priority, according to the Cahn–Ingold–Prelog priority rules (CIP), based on atomic number. When the center is oriented so that the lowest-priority substituent of the four is pointed a…
