5-Cholesten-24(RS)-methyl-3?-ol-25,26,26,26,27,27,27-d7

5-Cholesten-24(RS)-methyl-3?-ol-25,26,26,26,27,27,27-d7, also known as deuterated cholesterol, is a stable isotope-labeled form of cholesterol. It is used as a tracer in various research applications, including lipid metabolism studies and drug development. The deuterium-labeled cholesterol allows for precise measurements of cholesterol metabolism rates in vivo, providing insight into the mechanisms and pathways involved in cholesterol biosynthesis, absorption, and elimination. Deuterated cholesterol is a sterol, a type of lipid molecule that is an important component of cell membranes and a precursor to various hormones. The deuterated form has seven deuterium atoms, which replace seven hydrogen atoms in the cholesterol molecule. This modification does not alter the chemical properties or biological activity of cholesterol, but it allows for accurate tracking and quantification of cholesterol metabolism using mass spectrometry techniques. In addition to its use in research, deuterated cholesterol can also be used as a internal standard in clinical assays for cholesterol measurement. Its stable isotope labeling provides consistent and reliable results, improving the accuracy and precision of cholesterol quantification in biological samples. Overall, 5-Cholesten-24(RS)-methyl-3?-ol-25,26,26,26,27,27,27-d7 is a valuable tool for studying cholesterol metabolism and developing therapies for cholesterol-related disorders.
