Esempi di utilizzo di DIMERIZATION in una frase

• Unfortunately, instantaneous dimerization of the resulting phenol produces trace amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), an extremely toxic compound known to have both acute and chronic adverse effects.
• When the nucleophile and electrophile are different, the reaction is called a crossed aldol reaction; on the converse, when the nucleophile and electrophile are the same, the reaction is called an aldol dimerization.
• The acid-catalyzed dimerization of styrene to give a 1,3-diphenylbutene, which then can be transformed to the anthraquinone.
• The binding of extracellular growth factors to their receptor tyrosine kinases (RTK) triggers a conformational change and promotes dimerization and autophosphorylation of tyrosine residues on the cytoplasmic tail of the RTKs.
• The spontaneous dimerization of neat cyclopentadiene at room temperature to form dicyclopentadiene proceeds to around 50% conversion over 24 hours and yields the endo isomer in better than 99:1 ratio as the kinetically favored product (about 150:1 endo:exo at 80 °C).
• Several useful structural isomers of the octenes are obtained by dimerization of isobutene and 1-butene.
• The polypeptide segments containing these periodic arrays of leucine residues were proposed to exist in an alpha-helical conformation and the leucine side chains from one alpha helix interdigitate with those from the alpha helix of a second polypeptide, facilitating dimerization.
• This subunit is involved in the formation of the β-2 integrins (LFA-1, integrin alphaXbeta2/CR4/p150,95, and Mac-1/CR3) by dimerization with different CD11 subunits.
• Octafluorocyclobutane is produced by the dimerization of tetrafluoroethylene and the reductive coupling of 1,2-dichloro-1,1,2,2-tetrafluoroethane.
• Because the two benzene rings are in close proximity this cyclophane type also serves as guinea pig for photochemical dimerization reactions as illustrated by this example:.
• As early as 1909, the dimerization of anthracene into dianthracene was investigated as a means of storing solar energy, as well as the photodimerization of the naphthalene series.
• Mirex was produced by the dimerization of hexachlorocyclopentadiene in the presence of aluminium chloride.
• Alternatively, pelargonic acid can be produced in a two-step process beginning with coupled dimerization and hydroesterification of 1,3-butadiene.
• SMC proteins have two main structural characteristics: an ATP-binding cassette-like 'head' domain with ATPase activity (formed by the interaction of the N- and C- terminals) and a hinge domain that allows dimerization of SMCs.
• The parent phosphole readily rearranges by migration of H from P to carbon-2, followed by dimerization.
• This dimerization makes the κ-phases special as they are not quarter- but half-filled systems, driving them into superconductivity at higher temperatures compared to the other phases.
• In most of the BMP family heterodimers and homodimers form as the seventh cysteine is involved in the formation of a covalent bond, leading the dimerization.
• Along with the DBD, the LBD contributes to the dimerization interface of the receptor and in addition, binds coactivator and corepressor proteins.
• Structure-based design has also been employed to improve the cleavage specificity of FokI by modifying the dimerization interface so that only the intended heterodimeric species are active.
• Together with Claudins, and zonula occludens-1 (ZO-1), occludin has been considered a staple of tight junctions, and although it was shown to regulate the formation, maintenance, and function of tight junctions, its precise mechanism of action remained elusive and most of its actions were initially attributed to conformational changes following selective phosphorylation, and its redox-sensitive dimerization.
