Exempel på hur man kan använda ZWITTERIONIC i en mening

• HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent.
• The actual bonding picture of these types of ylides is strictly zwitterionic (the structure on the right) with the strong Coulombic attraction between the "onium" atom and the adjacent carbon accounting for the reduced bond length.
• Baeocystin, also known as norpsilocybin or 4-phosphoryloxy-N-methyltryptamine (4-PO-NMT), is a zwitterionic alkaloid and analog of psilocybin.
• Cocamide foaming agents include the nonionic cocamide DEA and cocamidopropylamine oxide, and the zwitterionic cocamidopropyl betaine and cocamidopropyl hydroxysultaine.
• The second step has also been proposed to be stepwise process, with chloride anion leaving first to produce a zwitterionic oxyallyl cation before a disrotatory electrocyclic ring closure takes place to afford the cyclopropanone intermediate.
• Solubilizing membrane proteins in their native state in conjunction with zwitterionic detergents such as CHAPS.
• CHAPS is a zwitterionic surfactant used in the laboratory to solubilize biological macromolecules such as proteins.
• The plant cells are subjected to a strongly alkaline solution containing a detergent (usually a zwitterionic or nonionic detergent such as Tween 20), and the mixture is incubated at high temperature.
• Rearrangement of this zwitterionic intermediate forms the ortho- sulfate (5), which then hydrolyses to form the ortho-hydroxyl aniline.
• The trans-cis-trans isomer of the König salt (6a) can react by either sigmatropic rearrangement or nucleophilic addition of a zwitterionic intermediate to give cyclized intermediate (7).
• The effects due to solvent on stabilizing the structures (conformers and zwitterionic species) of amino acids and peptides and the corresponding effects seen in the vibrational circular dichroism (VCD) and Raman optical activity spectra (ROA) have been recently documented by a combined theoretical and experimental work on L-alanine and N-acetyl L-alanine N'-methylamide.
• Similar to dysferlin and myoferlin, otoferlin has a FerA domain and its FerA domain has been shown to interact with zwitterionic lipids in a calcium-dependent manner and with negatively charged lipids in a calcium-independent manner.
• This acetalic detergent is split under acidic conditions into hexanol and the zwitterionic 3-acetyl-1-(3-sulfopropyl)pyridinium.
• Surfactants are classified into four main types, each with different properties and applications: anionic, cationic, nonionic and zwitterionic (or amphoteric).
• Zwitterions can be used to solve the fouling complications that arise from using PDMS, for PDMS is readily functionalized by zwitterionic polymers such as Poly(carboxybetaine methacrylate) (pCBMA).
• It utilizes a sulfonamide agonist headgroup, that confers high levels of intrinsic crystallinity that could relate to the acidic sulfonamide motif supporting a zwitterionic form in the solid state.
• In particular, he developed the Z scale for solvent polarity based on the solvatochromic effect for zwitterionic dyes and investigated bimane dyes as fluorescent labels.
• He developed the electronic theory of diradicals, as well as the concepts of diradical and zwitterionic states.
