The S stands for Svedberg units, which is the rate of sedimentation determined using a centrifuge. As I mentioned, the rate of sedimentation is not a linear process. It depends on several factors such as mass, shape and density of the macromolecule. What plays a role is the frictional forces on the surface of the molecule - and that surface will change if 2 macromolecules (in this case 30S and 50S) bind to each other.]]> 2021-11-03 12:09:01 UTC https://padlet.com/gss40uni/lcfz854ufqvzdbtk/wish/1864397213
