stigmasterol A80062 (Previously 700062) stigmasta-5,22-dien-3-ol

Stigmasterol is a plant sterol, a type of steroid that is found in various plant sources. Sterols are generally present at 0.1 percent levels in the majority of plant lipids. Sitosterol and stigmasterol are two sterols plants routinely produce, along with campesterol and cholesterol. These common plant sterols all aid in the development and stress management process of plants.

Stigmasterol belongs to the group of phytosterols or major sterols, which are natural compounds structurally similar to cholesterol. It is commonly found in vegetables, fruits, nuts, seeds, and some vegetable oils. It is particularly abundant in soybean oil and other legume oils.

Stigmasterol has a similar structure to dietary cholesterol, with a few differences in the side chain. Its chemical structure includes a sterol nucleus and a side chain.

It is present in various plant-based foods and food additives, including soybeans, sunflower seeds, peanuts, corn oil, and many other fruits, vegetables, and nuts. Its concentration can vary depending on the plant source. A major sterol in plasma membranes of plant cells, stigmasterol plays a role in regulating cell proliferation.

Along with other plant sterols, stigmasterol has been studied for its potential health benefits. Some research suggests that plant sterols may help lower blood cholesterol levels, particularly low-density lipoprotein (LDL) cholesterol. As a result, stigmasterol is sometimes included in functional foods and dietary intake supplements designed to support heart health.
