It has been introduced that trehalose has a possible role in cryptobionts, which are able to be back to life after complete dryness when it become wet again. The simple disaccharide prevents cell components such as proteins, cell membrane and nucleic acid from any damage of denaturation by dryness. It seemes that bonded water is replaced by trehalose on the surface of biomolecules without damage. The understanding for the mechanism is not known yet. Trehalose is a perfect preservative for the storage of unstable biological materials.
