WebChirality is commonly observed in nature and life, which exists at all length scales, from the molecular level (the single left- or right-handed amino acid) to the supramolecular level (the right-handed double helix of DNA), and up to macrobiomineralized materials (marine and snail shells) [314–317]. Chirality is a central theme in nature ...

WebAlmost all chiral molecules in living organisms are found in just one form: sugars are exclusively right-handed, amino acids left-handed and DNA coils into right-handed helices. Some think that this single-handedness, or homochirality, was a prerequisite for the formation of the replicating molecules that led to all life.

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.
