25-Hydroxyvitamin-D3-[23,24,25,26,27-13C5]

25-Hydroxyvitamin-D3-[23,24,25,26,27-13C5] is an isotopically labeled form of 25-hydroxyvitamin D3, which is a hormone that is produced by the liver and is vital for regulating calcium and phosphate levels in the body. This labeled form of the hormone is used in research and medical applications to study the metabolism of vitamin D3 and its effects on the body. The isotopic labeling of 25-Hydroxyvitamin-D3-[23,24,25,26,27-13C5] refers to the replacement of naturally occurring carbon atoms with carbon-13 isotopes. This labeling allows researchers to track the hormone's metabolism and its effects on different tissues and organs in the body. The hormone can be administered to patients through injection or oral supplements. Studies have shown that 25-Hydroxyvitamin-D3-[23,24,25,26,27-13C5] can be used to assess vitamin D status in individuals, as well as to determine the effectiveness of vitamin D supplements in treating various medical conditions. It has been found to be particularly effective in assessing vitamin D status in patients with kidney disease, as these patients often have low levels of the hormone. In conclusion, 25-Hydroxyvitamin-D3-[23,24,25,26,27-13C5] is a valuable tool for researchers and medical professionals in studying the metabolism and effects of vitamin D3 in the body. Its isotopic labeling allows for precise tracking and assessment of the hormone's effects on different tissues and organs, making it an essential component in various research and medical applications.
