WebBanavar et al.44, who found that fragments buried within globular proteins obeys the same Flory theorem45,46 derived for polymer melts, that is concentrated solutions of different chains. The same theorem has been shown to hold for fragments buried in the interior of single compact polymer chains, when selected with appropriate constraints47 ...

Webpects Flory theorem[8] to hold and the mean square sep-arations to scale as L1=2 as the short segments behave as a random walker. On the other hand, when the segments of equilibrium globule get larger, the nite size of the cu-bic lattice puts an upper limit on the possible values of R(L) and we expect its value to saturate. In contrast, WebJan 14, 2015 · Flory theorem is based upon the concept that the monomeric. excluded volume parameter in a melt of P-mers is screened by a. factor of 1/ P and, thus, very … baiuca grupo wikipedia
