Abstract :
Asp radical has enantiomeric d and l form, due to axis chirality. This pair of degenerate minima is occurring on a single 4D-Ramachandran Potential Energy Hyper Surface (PEHS). The βD and βL radicals are interconverted on a pair of enantiotopic paths of the 4D-PEHS each of which has a lower and a higher transition state. These barriers are always higher for the Asp in comparison to those of the Asn radical.
