Sterols and related compounds play essential roles in the physiology of eukaryotic organisms, and are essential for normal physiology of plants, animals, and fungi. [ 4 ] For example, cholesterol forms part of the cellular membrane in animals, where it affects the cell membrane's fluidity and serves as secondary messenger in developmental ...
The daily intake of stanols in the average western diet is about 60 mg/d, whereas the intake of plant sterols is about 150–300 mg/d and that of cholesterol is 500–800 mg/d. The relatively low natural levels of stanols in the diet are too low to have a significant effect on serum cholesterol levels.
Plant sterols and stanols, when compared head-to-head in clinical trials, have been shown to equally reduce cholesterol levels. [ 41 ] [ 42 ] [ 43 ] A meta-analysis of 14 randomized, controlled trials comparing plant sterols to plant stanols directly at doses of 0.6 to 2.5 g/day showed no difference between the two forms on total cholesterol ...
Sterol esters are a heterogeneous group of chemical compounds.They are created when the hydroxyl group of a sterol and a fatty acid undergo an esterification reaction. They can be found in trace amounts in every cell type but are highly enriched in foam cells and are common components of human skin oil.
Results indicated that incorporating sterols/stanols into the TLC diet produced positive changes in LDL cholesterol by 9.2%, total cholesterol by 7.4%, and triglycerides by 9.1%. A following study replicated this original study design, supporting the efficacy of 1.8 grams/day of esterified plant sterols/stanols in adjunct with the TLC diet to ...
Sterols are steroids in which one of the hydrogen atoms is substituted with a hydroxyl group, at position 3 in the carbon chain. They have in common with steroids the same fused four-ring core structure. Steroids have different biological roles as hormones and signaling molecules.

Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4]Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and signaling component of animal cell membranes.
