Document Summary
Bilayer vesicles : hydrocarbon tails of the molecules tend to lie in roughly which allows them to interact via van der waals interactions parallel arrays , Membrane bilayers : surround cells and that form partitions between cellular compartments: 4 acid - base equilibria. Behavior of all these molecules in biochemical processes depends strongly on their state of ionization. Acids and bases : proton donors and acceptors. Acids are proton (ht ) donors and bases are proton acceptors (cid:8869) strong acid dissociates almost completely into a proton and a weak conjugate base. * many biological molecules are weak acids or weak bases. The stronger the acid , the weaker its conjugate base (cid:8869) greater the tendency of an acid to donate a proton , the less its conjugate base tends to accept a proton and re - form the acid. Water has a slight tendency to ionize (cid:8869) can act as both a very weak acid and a very weak base.
