D- and L- forms of mirror image isomers, or enantiomers, are named according to their activity on polarized light. By using CROWNPAK CR-I(+) and CR-I(-) columns with chiral stationary phases, the D- and L-forms of amino acids can be analyzed separately. With CR-I(+) elution order is from D- to ... class e electrical fire extinguisher WebD-amino acids are used in racemic crystallography to create centrosymmetric crystals, which, depending on the protein, may allow for easier and more robust protein structure determination. Gramicidin is a polypeptide made up from mixture of D- and L-amino acids. Other compounds containing D-amino acids are tyrocidine and valinomycin.
