In this structure, half of the backbone hydrogen bonds are intramolecular.
It stabilises membranes by reacting with sulphydryl groups of membrane proteins forming stable mercaptides, thus preventing oxidation by inhibiting intramolecular disulphide formation.
The new conformations are stabilized by inter- and intramolecular hydrogen bonding.
It is during this phase that segment inversion occurs by intramolecular recombination between inverted repeats.
The exception alluded to above refers to a small number of crosslinks that are intramolecular (rather than intermolecular).
When these motions are frozen out at low temperature, the intermolecular contacts can ' tighten up ' more than the intramolecular ones.
The intramolecular interactions that govern the behaviour of allosteric enzymes are indeed many and complex.
This seems to be a less likely alternative than intramolecular energy transfer among aromatic amino acids and to the chromophore.
