In polymer chemistry, a random coil is a conformation of polymers where the monomer subunits are oriented randomly while still being bonded to adjacent units. It is not one specific shape, but a statistical distribution of shapes for all the chains in a population of macromolecules. The conformation's name is … Visa mer There are an enormous number of different ways in which a chain can be curled around in a relatively compact shape, like an unraveling ball of twine with much open space, and comparatively few ways it can be more … Visa mer • Protein folding • Native state • Molten globule Visa mer • polymer statistical mechanics • A topological problem in polymer physics: configurational and mechanical properties of a random walk enclosing a constant are Visa mer A real polymer is not freely-jointed.
