WebOct 4, 2024 · We also observed that the left-handed ΛΛ-P complex unthreads three times faster than ΔΔ-P. These results, along with a weaker binding affinity estimated for ΛΛ-P, suggest a preference in DNA binding to the chiral enantiomer having the same right-handed chirality as the DNA molecule, regardless of their common intercalating moiety. WebJul 11, 2024 · The "optical purity" is a comparison of the optical rotation of a pure sample of unknown stereochemistry versus the optical rotation of a sample of pure enantiomer. It is expressed as a percentage. If the sample only rotates plane-polarized light half as much as expected, the optical purity is 50%.
