[1-13C]cellobiose

[1-13C]cellobiose is a stable isotope-labeled compound used in various biochemical and biophysical studies. Cellobiose is a disaccharide composed of two glucose units linked by a β-1,4-glycosidic bond. The carbon atom labeled with 13C is the first carbon atom of the glucose unit attached to the β-1,4-glycosidic bond. The stable isotope label provides a tool for tracing the metabolic fate of the labeled molecule in cells and organisms. [1-13C]cellobiose is widely used as a substrate for studying the enzymatic hydrolysis of cellulose, which is the most abundant polymer on earth. The stable isotope label allows for the identification and quantification of the products of cellobiose hydrolysis, which can provide insights into the mechanism of action of cellulase enzymes. Additionally, [1-13C]cellobiose can be used to investigate the uptake and metabolism of cellulose by microorganisms. The stable isotope label enables the tracking of the carbon flux from cellobiose to various metabolic pathways and end products. In summary, [1-13C]cellobiose is a valuable tool for studying the enzymatic hydrolysis of cellulose and the metabolism of cellulose by microorganisms. Its stable isotope label provides a means of tracing the metabolic fate of the labeled molecule in cells and organisms.
