Sentence examples for central nitrogen from inspiring English sources

Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral).

This leads to weakening of the bond between central nitrogen and the side oxygen atoms of the adsorbed NO2 molecules.

The consecutive adsorption of NO2 molecules on the TiO2-supported Au overlayers probably produces N2 molecule formed from the central nitrogen atoms of the two adsorbed NO2 molecules.

Only the 408 complexes where the 3d metal ion is coordinated to the central nitrogen donor atom of this fragment are considered.

A series of novel aliphatic tripodal trithioether ligands 4 6 differing in the lengths of the alkyl chains between central nitrogen atom and sulfur donor function has been synthesized.

We hypothesise that if the central nitrogen atoms were suitably functionalised with enzyme-cleavable groups, then the associated change in shape could be exploited upon the removal of a group, and these compounds could thus be exploited as diagnostic probes for the detection of analytes (i.e., enzymes) in solution or biological samples.

The main peak can be ascribed to the two chemically non-equivalent nitrogens (four central nitrogens and four aza nitrogens), while the other peak is attributed to a shake-up satellite [11].

The distinguishing feature of thiopeptides is a central nitrogen-containing six-membered ring formed from two dehydroalanines [ 39].

Although there is a considerable variety in the presence of the central enzymes GS, G, GDH and GOGAT, and in the number of available transport systems for the central nitrogen-related metabolites, the composition of the GlnR regulon is relatively invariable between species.

Optimization of the side chain at the central aniline nitrogen of 7-amidino-2-naphthoanilide has led to several potent and orally active FXa inhibitors.

All the compounds possess a central basic nitrogen, but it is the nature of the basic centre, the substitution of aromatic rings and the spatial orientation of chemical groups that determines subtype selectivity profile [29].
