WebRibosomes in the cytoplasm of eukaryotic cells have a sedimentation coefficient of about 80 S (MW about 4.5 x 10 6) and are composed of 40 S and 60 S subunits. In prokaryotic cells, ribosomes are typically about 70 S (MW about 2.7 x 10 6) and are formed from 30 S and 50 S subunits. Eukaryotic ribosomes are also known as 80S ribosomes, referring to their sedimentation coefficients in Svedberg units, because they sediment faster than the prokaryotic ribosomes.
