[UL-13C4]erythritol

[UL-13C4]erythritol is a stable isotope-labeled compound that is commonly used in scientific research. It is a type of sugar alcohol that is derived from glucose, and it is often used as a low-calorie sweetener in various food products. The stable isotope labeling of this compound allows for precise measurements and tracking of its metabolic fate in biological systems. Chemically, [UL-13C4]erythritol is a four-carbon sugar alcohol with four hydroxyl groups (-OH) attached to its carbon backbone. It is a white, crystalline powder that is soluble in water and has a sweet taste. It is metabolized differently than other sugar alcohols, as it is absorbed in the small intestine and excreted unchanged in the urine, making it a popular choice for individuals with diabetes or those looking to reduce their caloric intake. In scientific research, [UL-13C4]erythritol is commonly used in metabolic studies to track glucose metabolism and to measure the rate of protein synthesis in cells. It is also used in studies of gut microbiota, as it is not metabolized by most bacteria in the gut. The stable isotope labeling of this compound allows for precise measurements of its metabolic fate in these studies. Overall, [UL-13C4]erythritol is a valuable tool in scientific research and a popular low-calorie sweetener in food products. Its stable isotope labeling allows for precise measurements and tracking of its metabolic fate, making it a valuable compound in various fields of research.
