Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Full conformational analysis of 1′-deoxyribose the model sugar residue of ribonucleosides is
performed by means of density functional theory at MP2/6–311++G (d, p) // DFT B3LYP/6–
31G (d, p) level. It is established that only four conformers (three of S- and one of N-type) over
the full number of 112 may be incorporated into the periodic structure of a two-strand RNA
molecule. The main geometric, energetic, and polar characteristics of all 112 stable conformers
are presented, as well as conformational equilibria under normal conditions. By the quantum
mechanical electron density topology analysis method (Bader’s Atoms-in-Molecules theory), as
many as six types of intramolecular hydrogen bonds are established in all possible conformers
of the isolated 1′-deoxyribose molecule. Namely, these are C1′H2 . . . O5′, C2′H . . . O5′, O2′H
. . . O3′, O3′H . . . O2′, O3′H . . . O5′, and O5′H . . . O3′.
