WebA comparison of the hydrodynamic radius to other types of radii can be shown using lysozyme as an example (see Figure 2). molecular weight of the protein is 14.7 kDa, with a partial specific volume or inverse density of 0.73 mL/g. The radius of gyration (R g) is defined by the expression given below, where m i is the mass of the i Whether a polymer is flexible or not depends on the scale of interest. For example, the persistence length of double-stranded DNA is about 50 nm. Looking at length scale smaller than 50 nm, it behaves more or less like a rigid rod. At length scale much larger than 50 nm, it behaves like a flexible chain.

[3] The theoretical hydrodynamic radius arises in the study of the dynamic properties of polymers moving in a solvent. It is often similar in magnitude to the radius of gyration. how many books has julia quinn written
