| sedimentation c. |
the velocity at which a particle sediments in a centrifuge divided by the applied centrifugal field, the result having units of time (velocity divided by acceleration), usually expressed in Svedberg units (S), which equal 10-13 second. Sedimentation coefficients are used to characterize the size of macromolecules, e.g., 5.8S rRNA, 22S rRNA; they increase with increasing mass and density and are higher for globular than for fibrous particles. Called also sedimentation constant.

| sedimentation r. |
