||From Rob Phillips and Ron Milo, "A Feeling for the Numbers in Biology", in press: With water content of about 70% (BNID 100044) the measured dry mass is ~0.3-0.5 pg (BNID 103892). The elemental composition of E. coli is such that about half the mass is carbon (BNID 100649) and therefore there are about 10^10 carbon atoms per cell (BNID 103010). Thus it requires the carbons from about ~2×10^9 glucose molecules to make a new cell when considering only the required carbon building material.
