Svedberg sedimentation coefficient

Svedberg - Wikipedi

A Svedberg unit (symbol S, sometimes Sv) is a non- SI metric unit for sedimentation coefficients. The Svedberg unit offers a measure of a particle 's size indirectly based on its sedimentation rate under acceleration (i.e. how fast a particle of given size and shape settles to the bottom of a solution) The term sedimentation coefficient describes the rate of sedimentation of a molecule for a given angular acceleration. It is expressed in seconds In order to avoid the exponents we use : 1 Svedberg = 1*10^-13 sec. Then the molecule has the sedimentation value of 10S Een svedberg is 10 −13 s. De sedimentatiecoëfficiënt normaliseert de sedimentatiesnelheid van een deeltje naar zijn toegepaste versnelling. Het resultaat hangt niet langer af van versnelling, maar alleen van de eigenschappen van het deeltje en de vloeistof waarin het is gesuspendeerd

Sedimentation coefficients have units of sec. 10 -13 sec is called 1 Svedberg (or 1 S). m = particle mass f = frictional coefficient of the particle in the solvent p = density of solutio For convenience, a unit called the Svedberg unit (named in honor of T. Sved­berg), abbreviated S, is used to describe sedimenta­tion coefficients and is equal to the constant 10-13 sec­onds. Thus, most cellular proteins have sedimentation coefficients between 1 and 200 S

Le coefficient de sédimentation a des unités de temps, exprimées en svedberg. Un svedberg vaut 10 −13 s. Le coefficient de sédimentation normalise la vitesse de sédimentation d'une particule à son accélération appliquée Sedimentation coefficients are usually expressed in terms of Svedberg units, one Svedberg unit being 10 −13 sec. The sedimenting molecules tend to diffuse. Diffusion is itself a transport process when the driving force is the gradient in chemical potential The Svedberg unit (Symbol S) is a measure of the sedimentation rate of a particle when centrifuged. More precisely, it is a measure of time and is equal to the value of 100 femtoseconds (10-13 seconds). The sedimentation rate indicates the size of the molecule, with the larger moleculeshaving a larger sedimentation coefficient

Theodor Svedberg (1884-1971) won the Nobel Prize in Chemistry in 1926; he deserved the award just for surviving the dangerous early instruments The sedimentation coefficient has the dimensions of a unit of time and is expressed in svedbergs. One svedberg is defined as exactly 10 −13 s . Essentially the sedimentation coefficient serves to normalize the sedimentation rate of a particle by the acceleration applied to it Hence, it is generally possible to define a sedimentation coefficient that depends only on the properties of the particle and the surrounding fluid. A Svedberg unit (symbol S, sometimes Sv) is a non-metric unit for sedimentation coefficient.
