Document Summary

There is no ph 0, it does not exist. ph can; however, approach 0. Buffers: make solutions resistant to changes of ph since they can react w/ acids and bases, made of a solution of weak acid and its conjugate base, illustrate law of mass action and le chateliers principle. This is an example of a titration curve that also gives you the reactivity of a molecule at a given ph and protonation state at any given ph. All made the same way in all living organisms (more or less) Advantage - we can consume other biochemicals by other organisms. Structural - same name, groups in different positions - different chemical properties. Enantiomers (optical isomers) - mirror images - same chemical properties. Attached to many membrane proteins and lipids to provide identity. 2^4 = 16 x 2 (ring forms) = 32 optical isomers and diastereomers. Ring form occurs in aqueous solution (99. 98% vs. 0. 02%)
