Method |
Note-in note 'c' beneath table the primary source is cited as assuming that 70% of cell weight is water, however this value wasn't located in primary source. |
Comments |
For water content of 74% see BNID 105482. Table gives general information on quantities of macromolecules per cell. Note 'c': "The wet weight is calculated from the assumption that 70% of E. coli protoplasm is water. The total dry weight per cell is 2.8×10^-13 g. The water content (assuming that 70% of the cell is water [primary source]) is 6.7×10^-13 g The total weight of one cell is 9.5×10^-13 g." For water fraction by volume in yeast and mammalian cell see BNID 105094, 103960, respectively. For water fraction by mass in yeast see BNID 103689 |
