It was concluded therefore, that PLB could not attack the sn-2 ester linkage of unnatural enantiomeric
PC but attacked the sn-3 ester linkage non-stereospecifically.
EQO is a chiral molecule existing as both R and S enantiomeric
excess (ee) was determinated by GC using a GC Varian 3800 with chiral adsorbent Astec Chiraldex B-PM.
Activity assays for a number of classes of primarily hydrolytic enzymes are covered including hydrolases, lipolytic enzymes, proteases, and enantiomeric
Currently, synthetic routes to synthesize the unnatural analogs of the [alpha]-amino acids easily, inexpensively, and with sufficient enantiomeric
yields does not exist.
Beetle pheromone chemistry is somewhat unusual as compared to other insects, in that enantiomeric
composition may play a critical role in defining the activity of the pheromone.
The chiral derivatization reagent R-(-)-[alpha]-methoxy -[alpha]-(trifluoromethyl)-phenylacetyl chloride [(R)-MTPCl] (ChiraSelect grade, 99% purity, 99.5: 0.5 enantiomeric
ratio) was obtained from Sigma-Aldrich (St.
Sorption and binding ability was studied along with the permeation selectivity of underivatized enantiomeric
solution of Phe using Ultrafiltration experiments.
PLA's crystalline properties are governed by its enantiomeric
composition characterized by its L:D ratio.
In vitro antiviral activity of three enantiomeric
sesquiterpene lactones from Senecio species against hepatitis B virus.
determination of D-2-hydroxyglutarate (D-2-HG)  and L-2-hydroxyglutarate (L-2-HG) is the only reliable test for the differential diagnosis of D-2-hydroxyglutaric aciduria (D-2-HGA), L-2-hydroxyglutaric aciduria (L-2-HGA), and the combined D/L-2-hydroxyglutaric aciduria (D/L-2-HGA).
