Biological Molecules - Phosphorus Compounds

Description

  • structure of phosphoric acids (anhydrides and esters)
    • phosphoric acid molecule
    • Phosphoric acid = H3PO4
    • phosphoric acid anhydride - pyrophosphate
    • Pyrophosphate is the simplest phosphoric acid anhydride.
    • phosphoric acid esters in biological molecules DNA and ATP
    • Phosphodiester bonds link together the DNA and RNA backbone.
    • Phosphoester bonds link the phosphates to the sugar in ATP.

Important reactions

  • Wittig reaction
    • Wittig reaction with mechanism
    • Carbonyl + Phosphorus Ylide → Alkene
    • The C1=O + Ph3P=C2 → C1=C2
    • Most Wittig reactions are not stereospecific.
