Phosphorus is Essential to All Living Organisms
There is No Substitute for Phosphorus
P 15
Phosphorus is a building block of DNA, cellular membranes and energy metabolism
The human adult body contains approx. 3.3 lbs (~2%) phosphorus, mostly in teeth and bones
There is no known substitute for phosphorus
"...for phosphorus, there is neither substitute nor replacement." - Isaac Asimov
“We may be able to substitute nuclear power for coal, and plastics for wood, and yeast for meat, and friendliness for isolation - but for phosphorus there is neither substitute nor replacement.”
