Plant sterols have diverse composition; they exist as free sterols, sterol esters with higher fatty acids, sterol glycosides, and acylsterol glycosides, which are absent in animal cells. This diversity of types of phytosterols determines a wide spectrum of functions they play in plant life.

10 Αυγ 2016 · Sterols are precursors of a group of plant hormones, the brassinosteroids, which regulate plant growth and development. Furthermore, sterols participate in transmembrane signal transduction by forming lipid microdomains. The predominant sterols in plants are β-sitosterol, campesterol, and stigmasterol.
Sterols are minor components of human dietary lipids, comprising the major portion of the unsaponifiable fraction of most edible fats and oils and can be classified according to their origin as animal or plant sterols (PS).
Plant sterols, also known as phytosterols, are a diverse group of sterols with distinct structural properties that play critical functions in plant life. These chemicals are widely dispersed throughout the plant kingdom and perform a variety of important activities in plant physiology.
Plant sterols are important components of the cell membrane and lipid rafts, which play a crucial role in various physiological and biochemical processes during development and stress resistance in plants.
1 Απρ 2018 · Phytosterols (plant sterols) occur in the cells of all plants. They are important structural components that stabilize the biological membranes of plants. Sterols can occur in the “free” unbound form or they can be covalently bound via an ester or glycosidic bond.
The purpose of this review is to provide and overview of plant sterols and their role in health and disease. Included will be a discussion of the genetics of sitosterolemia, the role of plant sterols as markers for premature atherosclerosis, and potential treatment options for lowering plant sterol levels in the body.
