What is the function of sterols in the body?
Sterols play a vital role in cell signalling by helping regulate the process of development. In addition, they pass on messages received from outside the cell to effect changes inside the cell. In this capacity, they are known as second messengers.

What is the most common type of sterol?
The most familiar type of animal sterol is cholesterol, which is vital to cell membrane structure, and functions as a precursor to fat-soluble vitamins and steroid hormones.
Is olive oil a sterol?
The main sterols found in olive oil were β-sitosterol, Δ(5) -avenasterol, campesterol and stigmasterol, most of them showing high variability.
Are steroids and sterols the same?
Sterols are a subgroup of steroids to which cholesterol belongs. Sterols are important not only to humans, but also to plants. For example, plants have cholesterol, too.

What are the side effects of plant sterols?
What is the most important zoosterol in the human body?
The most important zoosterol is cholesterol; notable phytosterols include campesterol, sitosterol, and stigmasterol. Ergosterol is a sterol present in the cell membrane of fungi, where it serves a role similar to cholesterol in animal cells.
What are sterols in phytosterols?
Cholesterol is the main zoosterol, but sterols in plants commonly occur as mixtures with β -sitosterol, campesterol, and stigmasterol representing three of the major phytosterols. These sterols are all Δ 5 -sterols ( Figure 6 ), but Δ 7 -sterols may also be present in small quantities ( Table 1 ).
What are sterols of plants and animals?
Sterols of plants are called phytosterols and sterols of animals are called zoosterols. The most important zoosterol is cholesterol; notable phytosterols include campesterol, sitosterol, and stigmasterol.
What is a sterol?
