Description

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.

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.
