    Discovery of PhosphorusInteresting Facts About PhosphorusUses of PhosphorusAbundance and IsotopesHennig Brand discovered phosphorus in 1669, in Hamburg, Germany, preparing it from urine. (Urine naturally contains considerable quantities of dissolved phosphates.) Brand called the substance he had discovered ‘cold fire’ because it was luminous, glowing in the dark. Brand was an alchemist and, like other alchemists, he was secretive about his methods. He did not reveal his method publicly, choosing instead to sell it to Johann Da在chemicool上查看更多信息

  • Phosphorus acquisition and use: critical adaptations

    Phosphorus stress can severely limit the activity of pyruvate kinase (PK), an enzyme requiring P i and ADP. The PEPC, MDH and NAD‐malic enzymes can bypass PK and thus maintain the flow of carbon from glycolysis to the TCA cycle by avoiding the use of ADP but generating free P i ( Theodorou et al ., 1992 ; Plaxton Carswell, 1999 ).
