sitosterol-d7 700148 (24-ethyl)-heptadeuteriostigmast-5-en-3ß-ol

Sitosterol-d7 is a deuterated derivative of β-sitosterol, a naturally occurring phytosterol found in plants, regulating the embryonic phase. Phytosterols, including beta-sitosterol-d7 (mixture of diastereomers), share structural similarities with cholesterol—and are known for their potential health benefits, particularly in cholesterol metabolism and cardiovascular health.

The "d7" in sitosterol-d7 indicates that seven hydrogen atoms in the molecule have been replaced with deuterium, a stable, non-radioactive isotope of hydrogen. Like beta-sitosterol, sitosterol-d7 maintains a structural resemblance to cholesterol. This similarity allows it to compete with cholesterol for absorption in the digestive system.
