α,β-[1,1'-D2]trehalose

? , ? -[1,1'-D2] trehalose is a deuterium-labeled disaccharide that is commonly used in biochemical and biophysical research. Trehalose is a non-reducing disaccharide composed of two glucose molecules linked by an α,α-1,1-glycosidic bond. It is widely distributed in nature and is commonly found in bacteria, fungi, plants, and invertebrates. Trehalose is known to play a protective role against various environmental stresses, such as desiccation, freezing, and heat stress. The deuterium-labeled form of trehalose, ? , ? -[1,1'-D2] trehalose, is often used as a tracer molecule in studies related to trehalose metabolism and transport. It can be used to investigate the biosynthesis of trehalose in vivo, as well as to explore the mechanism of trehalose uptake and utilization by cells. Chemically, the deuterium-labeled trehalose is identical to the natural form of trehalose, except that two of the hydrogen atoms in the molecule are replaced by deuterium atoms. This substitution does not significantly alter the properties of the molecule, but it does allow for the molecule to be easily distinguished from the natural form using mass spectrometry techniques. In summary, ? , ? -[1,1'-D2] trehalose is a valuable tool for investigating the metabolism and transport of trehalose in biological systems. Its use as a tracer molecule allows researchers to gain a deeper understanding of the roles that trehalose plays in protecting cells against environmental stresses.
