Chemistry, like all the natural sciences, Safety of H-Asp-OH, begins with the direct observation of nature¡ª in this case, of matter.56-84-8, Name is H-Asp-OH, SMILES is N[C@@H](CC(O)=O)C(O)=O, belongs to amides-buliding-blocks compound. In a document, author is Lovato, Kaitlyn, introduce the new discover.
Restricted amide rotation with steric hindrance induced multiple conformations
The C-N bond character is dependent directly upon the resonance-contributor structure population driven by the delocalized nitrogen lone-pair of electrons. In the case of N, N-dibenzyl-ortho-toluamide (o-DBET), the molecule adopts subpopulations of conformers with distinct NMR spectral features, particularly at low temperatures. This conformational adaptation is unique to o-DBET, while the corresponding meta- and para- forms do not show such behavior. Variable-temperature (VT) NMR, two-dimensional exchange spectroscopy (EXSY), and qualitative molecular modeling studies are used to demonstrate how multiple competing interactions such as restricted amide rotation and steric hindrance effects can lead to versatile molecular adaptations in the solution state.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 56-84-8. Safety of H-Asp-OH.
