arsenic life? (Introduction)
Emphatically NO:-http://www.washingtonpost.com/national/health-science/journal-retreats-from-controversial-arsenic-paper/2012/07/08/gJQAFQb7WW_story.html?wpisrc=nl_headlines-But the explanation of the mixup lies in the relation of phosphorus and arsenic. They are close chemically, but only phosphous is used for energy as ATP, adenosine tri-phosphate, the main energy source in life. How did phosphorous get added to orginal life? No one knows. Inorganic phosphorus is difficult to get at.-"Contemporary organisms use, almost exclusively, orthophosphate derivatives (PO4 3-) in their cell biochemistry,1 yet thorny questions remain as to how Nature was able to accumulate, activate and exploit the orthophosphate group from geological sources with both poorly solubility and low chemical activity"-http://www.lpi.usra.edu/meetings/abscicon2010/pdf/5264.pdf-Further explanation:- http://www.sciencedaily.com/releases/2010/05/100525094906.htm
