Grana membrane

Fig. 9.11 The INS spectra of hydrated grana membrane. Whilst the 100% hydration (upper spectrum) resembles ice Ih, Fig. 9.8, at lower hydration the spectra are modified. Reproduced from [42] with permission from the American Chemical Society.

In DNA the transition from interfacial to bulk water occurs after ca 1 layer but grana membranes retain interfacial water up to ca 2 layers on each surface. Similarly the water in close contact with gelatine and chitosan did not have the ice Ih structure [43].
