They are characterized by an increasing optical rotation towards short wavelengths in the ultraviolet range of the spectrum and show a negative slope. Negative ORD plain curves are for negative values of the optical rotation and show a positive inclination with more negative values towards shorter wavelengths. Achiral molecules and racemic mixtures are not optically active resulting in ORD curves with [α ] = 0 over the whole wavelength range. If one enantiomer of a given chiral molecule presents a positive ORD curve, the other enantiomer does necessarily present a negative ORD curve.
ROSETTA’s “Chirality-Module” will moreover try to shed some light on all the theories on the origin of biomolecular asymmetry. Doing so, it might contribute to the elucidation of the ultimate cause of the spectacular biochirality phenomena on Earth. Chapter 2 Stereochemistry for the Study of the Origin of Life Before exploring up-do-date theories and cutting-edge research activities on the origin of life’s molecular asymmetry, this Chap. 2 will provide a brief, comprehensible, and illustrated introduction on common stereochemical terms like chirality, stereogenic center, enantiomer, racemic mixture, optical activity, and homochirality.
Any enantiomerically pure compound that could be related by chemical transformation processes to (+)-D-glyceraldehyde is categorized as D-enantiomer, and any compound that corresponds to (−)-L-glyceraldehyde is categorized L-enantiomer. 3 Stereochemical Nomenclature 27 Fig. 7 Chemical structures of (−)-L-glyceraldehyde (left) and (+)-D -glyceraldehyde (right) used for labelling D - and L-enantiomers denominating D or L by often complex and multiple chemical transformation processes is habitually slow and work-intensive.
