25-Hydroxyvitamin D2-[25,26,27-13C3]

25-Hydroxyvitamin D2-[25,26,27-13C3], also known as 25(OH)D2-[25,26,27-13C3], is a stable isotope labeled version of 25-hydroxyvitamin D2, a metabolite of vitamin D2. This compound is used in various research studies to investigate the metabolism and distribution of vitamin D2 in the body. Vitamin D2 is a fat-soluble vitamin that is essential for the maintenance of bone health and calcium homeostasis. It is obtained from dietary sources such as fortified foods and supplements or synthesized in the skin upon exposure to sunlight. Once absorbed, vitamin D2 is converted to 25-hydroxyvitamin D2 in the liver, which is the major circulating form of vitamin D in the body. The stable isotope labeled 25(OH)D2-[25,26,27-13C3] is used to study the metabolism of vitamin D2 in the body by using mass spectrometry techniques. This compound is used as an internal standard in quantifying levels of vitamin D2 and its metabolites in biological samples. It is also used to investigate the distribution and metabolism of vitamin D2 in different tissues and organs. In conclusion, 25-Hydroxyvitamin D2-[25,26,27-13C3] is a useful tool in investigating the metabolism and distribution of vitamin D2 in the body. Its usage in research studies provides valuable insights into the role of vitamin D2 in maintaining bone health and preventing various diseases associated with vitamin D deficiency.
