"WebAsymmetric carbon atoms cause chirality in molecules – the possibility of two mirror image forms. Almost 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 ... " - Chirality of molecules
