Although we can't directly compare sedimentation constants and molecular weights it is helpful to have a rough idea of the corresponding ranges. A value of 2S will be obtained for nearly spherical proteins with molecular weights somewhat over 10,000; long, thin molecules having sedimentation constants of 2S may have molecular weights over 50,000. Similarly, 4S crudely corresponds to a molecular weight of 50,000 for spherical proteins, 8S to 160,000 and 16S to 400,000; the molecular weights of long, thin molecules with the same sedimentation constants are several-fold greater. 3, record 1, English, - Svedberg%20unit

La plupart des protéines ont un S compris entre 1 et 200. A partir de S on peut estimer la masse moléculaire à l'aide de l'équation de Svedberg : [...] où N est le nombre d'Avogadro, p la densité du milieu de centrifugation, [...] le volume spécifique partiel de la protéine et f le coefficient de friction de la protéine qui est une fonction compliquée de la conformation de la protéine (forme, dimensions, rigidité, degré de solvatation préférentielle). 3, record 1, French, - Svedberg
