Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Safety of H-Gly-NH2.HCl, 1668-10-6, Name is H-Gly-NH2.HCl, molecular formula is C2H7ClN2O, belongs to amides-buliding-blocks compound. In a document, author is Gao, Xiao-hui, introduce the new discover.
Tyrosine-containing cyclic dipeptides based on a diketopiperazine (DKP) ring are studied under jet-cooled conditions using resonance-enhanced multi-photon ionisation (REMPI), conformer-selective IR-UV double resonance vibrational spectroscopy and quantum chemical calculations. The conformational landscape of the dipeptide containing natural L tyrosine (Tyr), namely c-LTyr-LTyr strongly differs from that of its diastereomer c-LTyr-DTyr. A similar family of conformers exists in both systems, with one aromatic ring folded on the dipeptide DKP ring and the other one extended. Weak NH and CH interactions are observed, which are slightly different in c-LTyr-LTyr and c-LTyr-DTyr. These structures are identical to those of LL and LD cyclo diphenylalanine, which only differ from c-Tyr-Tyr by the absence of hydroxyl on the benzene rings. While this is the only conformation observed for c-LTyr-DTyr, c-LTyr-LTyr exhibits an additional form stabilised by the interaction of the two hydroxyls, in which the two aromatic rings are in a stacked geometry. Stereochemical effects are still visible in the radical cation, for which one structure is observed for c-LTyr-DTyr, while the spectrum of the c-LTyr-LTyr radical cation is explained in terms of two co-existing structures.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1668-10-6. Safety of H-Gly-NH2.HCl.
