Primary nucleation
Did you know?
WebNucleation – Nucleation is that the initiation of a phase transition during a small region, like the formation of a solid crystal from a liquid solution. Total nucleation is the sum effect of two categories of nucleation – primary and secondary. Primary nucleation – This is the step, where the initial formation of a crystal occurs. WebHere, we discuss a case of membrane-mediated nucleation that leads to β-aggregation. We studied the membrane-mediated conformation changes of the peptide penetratin, and the results of our study led us to a free-energy description for a membrane-mediated version of the Jarrett-Lansbury model. Like the prototype β-amyloid peptide Alzheimer's ...
WebIn particular, it has been shown that, once a small but critical concentration of aggregates has formed through the self-assembly of Aβ42 monomers as a result of primary nucleation events, surface-catalyzed secondary nucleation becomes important because the surfaces of existing fibrils can catalyze the generation of new oligomeric species . WebSecondary nucleation is thus not the same as heterogeneous primary nucleation (Fig. 1b), which happens in the vicinity of foreign surfaces of for example phosholipid membranes …

While it is well-established that the newly added monomer in fibril elongation adopts the conformation of the monomers in the seed ("templating"), it is unclear whether fibrils formed through secondary nucleation of monomers on the surface of seed …
