What are the properties of plant sterols

Phytosterols, also known as phytosterols, belong to plant steroids. The main components of plant sterols include sitosterol, campesterol, stigmasterol, rapeseed sterol and corresponding alkanols, etc., all of which use cyclopentane perhydrophenanthrene as the main framework and contain alcohol groups. They are related to cholesterol. The difference in structure is that there are more side chains on C24. For example, sitosterol has an ethyl group on C24, campesterol has a methyl group on C24, and the structure of stigmasterol is the same as that of sitosterol. It's just that there is a double bond on C22. Plant foods with higher plant sterol content include plant oils, nuts, seeds, beans, etc. The content of plant sterols in vegetable oils is highest in corn germ oil, followed by sesame oil; pistachios content is highest in nut seeds, followed by black sesame; soybeans have the highest content, followed by green beans; vegetables, fruits and potatoes are plant solids. The alcohol content is low.
