  2. Protactinium - Wikipedia

    Heating it to higher temperatures in an inert atmosphere decomposes Pa(PO 3) 4 into the diphosphate PaP 2 O 7, which is analogous to diphosphates of other actinides. In the diphosphate, the PO 3 groups form pyramids of C 2v symmetry. Heating PaP 2 O 7 in air to 1400 °C decomposes it into the pentoxides of phosphorus and protactinium. [58]

  9. Phosphatidic acid - Wikipedia

    en.wikipedia.org/wiki/Phosphatidic_acid

    PA is a vital cell lipid that acts as a biosynthetic precursor for the formation (directly or indirectly) of all acylglycerol lipids in the cell. [11] In mammalian and yeast cells, two different pathways are known for the de novo synthesis of PA, the glycerol 3-phosphate pathway or the dihydroxyacetone phosphate pathway. In bacteria, only the ...
