Flory theorem
WebHint: Compare the density of PS (pps = 1040 kg/mº) with the density of a single chain with a pervaded volume V. (b) According to the Flory theorem, the size scaling of polymers in the melt is ideal (i.e., R~N1/2). WebJun 21, 2005 · Proteins, chain molecules of amino acids, behave in ways which are similar to each other yet quite distinct from standard compact polymers. We demonstrate that the Flory theorem, derived for polymer melts, holds for compact protein native state structures and is not incompatible with the existence of structured building blocks such as α helices …
