The Structure of Proteins: Two Hydrogen-bonded Helical Configurations of the Pol Ypeptide Chain

Consideration of C-H…O interaction in the heterocyclic organic-inorganic hybrid material: tri-prolinium12- phosphomolibdate heteropolyoxometalate

Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in g...

Rationalizing the Strength of Hydrogen-Bonded of Molybdate-Phosphonic acid Complex (1:2): Density Functional Theory Studies

The relative stability of hydrogen-bonded of Molybdate-Phosphonic Acid (MPA) complex (1:2) ingas phase has been carried out using Density Functional Theory (DFT) methods. The methods are usedfor calculations are B3LYP, BP86 and B3PW91 that have been studied in two series of basis sets: D95**and 6-31+G(d,p) for hydrogen and oxygen atoms; LANL2DZ for Mo and Phosphorus.
