4- AROMATICS (PHENOLS)

decarboxylation happens when you add heat CO2 exits as a gas, that is not a reversible process

the reagent is a reduced form a phenolphthalein, which has no color if there is blood the reaction will be catalysed by hemoglobin, which has iron and there is an oxidation reaction if there is blood it turns pink iron goes from 3+ to 2+

lots of conjugation, which reflects light in the visible region

colouring cloths, solvents, oiles and waxes

6 member ring with 2 carbonyls

by using strong oxidizing agents?

redox reactions quinones are good oxidising agents strip electrons from molecules, become reservoirs for electrons nature makes use of these reversible redox reactions to transport electrons from one substance to another in enzyme catalysed reactions

electron acceptor molecules, has a benzoquinone in it has a long isoprenoid tail, usually there are 10 units longer than the width of the bilayer, can be folded to give a more compact structure the tail is lipid like (hydrophobic) can reside in the core of the membrane carries electrons from complex 1 and 2 to complex 3 during oxphos

this will further stabilize the dianon and facilitate the forward reaction it will now become an even stronger oxidizing agent
