一般描述

D-(+)-Trehalose is a disaccharide composed of two α-glucose units. It is used as a cryoprotectant in a variety of cell freezing media. Used as a protectant in transportation media. It predominantly exists among the species that support anhydrobiosis (life without water). It serves as a carbohydrate reserve in microorganisms and protects them from adverse conditions, such as heat, cold, dehydration, desiccation, and oxidation. Trehalose acts as a chemical chaperone affecting protein folding. It is known to prevent the generation of amyloids and accumulation of β-amyloid in vitro. A similar effect of trehalose has been observed with Huntingtin protein aggregation. Thus, it might serve as a protective agent in Alzheimer′s disease and Huntington′s disease. Trehalose stimulates the better initial growth of Salmonella cells.

应用

D-(+)-Trehalose can be used as a carbohydrate reserve in certain cell cultures to tide over environmental stresses. It can also be used in biopharmaceutical monoclonal antibody formulations and as a protein stabilizer.
