Sentence examples for polycyclic structure from inspiring English sources

Quantum chemical ab initio calculations of geometry and the principal values of 29Si NMR chemical shift tensor and the isotropic chemical shift confirmed our structural predictions that copolymers with polycyclic structure units are formed.

This result indicated that a ring fusion manner of the polycyclic structure is important to recognize membrane proteins.

The first one is a Stille reaction with a 3-trimethylstannyl-5-azaindole derivative and the second one a photochemical step leading to the proposed polycyclic structure.

When NO2 is used, the product NO can be recycled and used again to produce the reactant NO2.2HCN + NO2 → (CN 2 + NO + H2O Trace impurities in (CN 2 appear to facilitate polymerization at high temperatures (300 500 °C [600 900 °F]) to paracyanogen, a dark solid that has a polycyclic structure of six-membered rings of alternating carbon and nitrogen atoms.

Instead, the polycyclic structure adopts a C s symmetry.

Three distinct steps of fullerene formation can be identified: nucleation of polycyclic structures by entangled polyyne chains, growth by ring condensation of attached chains, and cage closure.

These modifications involve dehydration of several serine and threonine residues followed by intramolecular conjugate additions of cysteines, resulting in extensively cross-linked polycyclic structures.

Analysis of these polycyclic GMs showed that their polycyclic structures are formed based on the polyunsaturated terpenoid fraction.

Because of the presence of polyunsaturated terpenoid part, free radical reaction can be occurred in GMs under the conditions of enzyme and light, which led to the formation of polycyclic structures (Table 2).

Using this definition, many biologically important polycyclic structures, such as purines, pyrimidines, hemes or sterols, are obtained.
