Flory radius vs radius of gyration
WebNov 15, 2012 · The characteristic Rg/Rh value for a globular protein is ~0.775, which means that Rg is smaller than Rh. However, when molecules deviate from globular to non-spherical or elongated structures then Rg/Rh tend to values upwards of 0.775, as Rg becomes larger than Rh. Experimentally, it is important to remember that for proteins Rg cannot be ... WebGyroradius. The gyroradius (also known as radius of gyration, Larmor radius or cyclotron radius) is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field. In SI units, the non-relativistic gyroradius is given by. where is the mass of the particle, is the component of the velocity perpendicular to ...

However, the … Weband has been describe by Flory in terms of the Characteristic ratio for real chains. Doi demonstrates that short-range interactions do not modify the basic physics of a random walk in section 1.12 on pp. 4, for the condition that a chain is free to rotate to any site except the preceding step. The main point is that this type of exclusion on a ...

It has been known since Flory's seminal work in the mid-20th century that polymers show a power-law dependence, where the radius of gyration is proportional to the number of residues raised to a power.
Webto describe the size. This value is the radius of a sphere of an equivalent size to the molecule being measured. The two most commonly used values of molecular size are RH (hydrodynamic radius) and Rg (radius of gyration). The hydrodynamic radius is the radius of an equivalent sphere that diffuses at the same speed as the molecule under …
