Application:	D-(+)-Trehalose dihydrate has been used: • in trehalose test to stabilize pharmaceutical products • as a component of trehalose/sucrose solution for the preparation of J-aggregates • in the preparation of simulated honey sugar cocktail (SHSC) to study its effect on chemical and thermal stability of proteins
Biochem/physiol Actions:	Trehalose is a 1-alpha (disaccharide) sugar that supports plants and animals to withstand extended periods of desiccation. Trehalose acts as a cryoprotectant in a variety of cell freezing media. It serves as a primary carbon source and as a compatible solute accumulated as a response to osmotic stress and heat shock.
General description:	Trehalose is a non-reducing sugar, which is formed when two glucose units are joined by a 1-1 alpha bond. This disaccharide is present naturally in several organisms like both prokaryotes and eukaryotes.
