Biochem rxns

  1. types of bond cleavages for C-H bonds
    • homo- each atom gets one electron
    • hetero-one atom gets both e- and one gets none
  2. 7 common rxns in biochemistry
    • Nucleophilic substitution
    • Aldol condensation
    • claisen condensation
    • Decarboxylation
    • internal rearrangments
    • Elimination rxns
    • Free radical rnxs
  3. difference between aldol and claisen
    • aldol-c nuc w/ carbonyl + ketone= alcohol 
    • claisen-c nuc w/ carbonyl + ester=ketone
  4. thiolase
    • claisen condensation
    • SH on enzyme+
  5. enolase
    • water is removed from 2 phosphoglycerate to form phosphoenolpyruvate (double bond)
    • elimination rxn
  6. isomerization mech
    • base attracts proton opposite alcohol
    • forms double bond and another alchol
    • [two alcohols]
    • base attracts 1st alcohol H and forms double bond C-O abd hydrogen bond
