The structures to which a proton is added on the six-centered sites adjoining the hydrogen bonds are more prone to proton transfer in the gas phase, whereas a proton added on the minor groove and the sites adjoining the hydrogen bonds is favorable to the proton transfer in energy in the ...
The percentage of nitrogenous bases on double-stranded DNA which is either guanine and cytosine, a datum of interest to molecular biologists as guanine and cytosine bind to each other with 3 hydrogen bonds (in contrast to adenine and thymine, which share 2 hydrogen bonds), and thus is a benc...
We have also shown that positive charges adjacent to C–H bonds in the heterocyclic ring of nucleic acid bases polarise these bonds and enable them to take part in strong hydrogen bonds to appropriate acceptors.doi:10.1038/260807a0PARTHASARATHY, R...
GC/FID is responsive to compounds with carbon-hydrogen bonds only GC/FID is a destructive technique so no additional analysis can occur on the sample after it is performed Identification and quantitation is limited to the compounds for which reference standards are run ...
The recent novel understanding of soil humus (Piccolo 2002; Lehmann and Kleber, 2015; Wells, 2019) as a supramolecular association of relatively small (<1000 Da) heterogeneous molecules self-assembling by relatively weak forces (van der Waals, π-π, hydrogen bonds, cations bridged intermolecular...
NPD Overview– The NPD detector is highly selective, but only for Nitrogen and Phosphorus containing compounds. At first, a precisely controlled Hydrogen and Air mixture surrounds the NPD bead within the detector body. Secondly, a voltage is applied to the bead to activate the surface. Finally,...
The GC pair is bound by three hydrogen bonds, while AT pairs are bound by two hydrogen bonds. And so, The GC content affects the stability of DNA. The GC content affects the secondary structure of mRNA. The GC content affects the annealing temperature for template DNA in PCR experiments. ...
The increased stability of GC-rich DNA sequences is, contrary to popular belief, not primarily because of thehydrogen bonds. Stabilization is mainly due to stacking interactions called base stacking. There are some beautiful biochemistry and biophysics behind why this stacking occurs. (1) ...

Due to the formation of strong hydrogen bonds, which in this case belong to carboxylic acid dimers36, a wide range of vibrations originate from the ν(–OH) groups. A very clear band with a maximum at about ~ 1640 cm−1(Fig.2) corresponds, in turn, to the deformation vibrations...
