Naming[ edit ] The unit is named after the Swedish chemist Theodor Svedberg — , winner of the Nobel Prize  in chemistry for his work on disperse systems, colloids and his invention of the ultracentrifuge. Factors[ edit ] The Svedberg coefficient is a nonlinear function. It depends on the frictional forces retarding its movement, which, in turn, are related to the average cross-sectional area of the particle.
Bigger particles tend to sediment faster and so have higher Svedberg values. Svedberg units are not directly additive since they represent a rate of sedimentation, not weight. The svedberg is the most important measure used to distinguish ribosomes. Ribosomes are composed of two complex subunits, each of which includes rRNA and protein components. In prokaryotes including bacteria , the subunits are named 30S and 50S for their "size" in Svedberg units.
Within cells, ribosomes normally exist as a mixture of joined and separate subunits. The largest particles whole ribosomes sediment near the bottom of the tube, whereas the smaller particles separate 50S and 30S subunits appear in upper fractions.
