WebThe 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 molecules having a larger sedimentation coefficient. Web70S refers to the rate of sedimentation of the ribosome in a centrifuge. The "S" is a unit of measurement called the Svedberg unit. Ribosomes contain two subunits. In prokaryotes, …
