Control of Molecular Conformation and Crystal Packing of Biphenyl Derivatives.
ChemPlusChem, 2021This Review presents a discussion of the conformation of biphenyl derivatives in different chemical environments. The interplay between aromatic stabilization and steric repulsion, normally considered to explain the conformation of the molecule, is ...

Molecular Conformation of Inosine
Nature, 1969INOSINE is one of the rare nucleosides found in nucleic acids. It occurs especially in transfer ribonucleic acid where it appears to form part of a number of anticodons1,2. It can form a base pair with any one of the bases adenine, uracil or cytidine in the third codon1,2 position, and the possibility of atypical base pairs is part of the “wobble ...

Molecular Conformation of GABA
Nature New Biology, 1971CURTIS et al.1,2 have described evidence suggesting that the alkaloid bicuculline is a specific antagonist to the action of γ-aminobutyric acid (GABA), a possible inhibitory transmitter in the mammalian brain3,4. By considering structural models, they suggested3 as a stereochemical basis for this antagonism a geometrical configuration in which the N ...

Molecular Conformation of Deoxyuridine
Nature, 1971THE structure determination of deoxyuridine was undertaken as part of a series of conformational studies of nucleic acid components. Such studies give information about the preferred conformation of nucleosides and nucleotides1,2, and may clarify the conformational differences and changes that occur in nucleic acids.

Conformational Molecular Rectifiers
Nano Letters, 2004Unimolecular rectification based on voltage-controlled intramolecular stereochemical modification is suggested and computationally investigated. In sharp contrast to present molecular rectifiers, these conformational molecular rectifiers (CMRs) differ in principle from silicon structures, deriving their large, strongly temperature-dependent ...

Molecular Conformation and Hydrogen Bond Formation in Liquid Ethylene Glycol.
Journal of Physical Chemistry B, 2020The ethylene glycol (EG) molecule, HOCH2CH2OH, adopts a conformation where the central OCCO dihedral is exclusively gauche in the gaseous as well as crystalline states, but in the liquid, for close to 20 % of the molecules, the central OCCO adopts the ...

Molecular conformation of prostaglandin A1
Prostaglandins, 1973Abstract The crystal and molecular structure of prostaglandin A1 (PGA1) has been determined by X-ray diffraction. (Space group P212121, a = 18.10 A A , b = 21.09 A A , c = 5.42, Z = 4) . Comparison of the structure of PGA1 with that of PGF1β (determined previously as the tribromobenzoate) indicates significant ...

Molecular Conformations of 5-Iodouridine
Nature, 1970THE structure of unusual nucleic acid components is of importance in relation to conformational and model building studies on nucleic acids in general and those concerning tRNA in particular. In the case of 5-iodouridine (Fig. 1) it is particularly desirable to know the crystal structure in order to compare the effects of ionizing radiation on single ...

Molecular conformation of L-DOPA
Biochemical and Biophysical Research Communications, 1970Abstract The structure of L-DOPA, a biological precursor of melanins has been determined by a new systematic analysis of the Patterson function. Its molecular conformation is different from that so far reported for any aromatic aminoacid, peptide or related compound.
