Organic conjugation
In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability. It is conventionally represented as having alternating single and multiple bonds. Lone pairs, radicals or … Zobacz więcej Conjugation is possible by means of alternating single and double bonds in which each atom supplies a p orbital perpendicular to the plane of the molecule. However, that is not the only way for conjugation to … Zobacz więcej Cyclic compounds can be partly or completely conjugated. Annulenes, completely conjugated monocyclic hydrocarbons, may be aromatic, nonaromatic or antiaromatic. Aromatic compounds Compounds … Zobacz więcej • Resonance • Hyperconjugation • Cross-conjugation • Polyene • Conjugated microporous polymer Zobacz więcej The quantitative estimation of stabilization from conjugation is notoriously contentious and depends on the implicit assumptions that are made when comparing reference systems or … Zobacz więcej There are also other types of interactions that generalize the idea of interacting p orbitals in a conjugated system. The concept of hyperconjugation holds that certain σ bonds can also delocalize into a low-lying unoccupied orbital of a π system or an … Zobacz więcej In a conjugated pi-system, electrons are able to capture certain photons as the electrons resonate along a certain distance of p-orbitals - similar to how a radio antenna detects … Zobacz więcej Witryna12 paź 2015 · Conjugation. 1.

WitrynaThe conjugation of the APN-TMPP probe to a peptide increases retention time in LC-MS. Experiments to prove the chemoselectivity of APN for cysteine were carried out by reacting APN-TMPP with tryptic digest at a 200: 1 molar ratio of APN-TMPP to protein at 25 °C for 1 h. The peptide mixtures before and after tagging were analysed with LC-MS.
