Tag: Phytosterol

Over 250 types of phytosterols have been identified in plants, but the most well-known is often called by another name. When you ask, 'What is another name for sitosterol?', the most accurate and common answer is beta-sitosterol (β-sitosterol), a plant-derived compound with a similar chemical structure to cholesterol. This natural substance is gaining attention for its potential to lower cholesterol and provide other health benefits.

Sterols are amphipathic lipids found in almost all eukaryotic cell membranes, and understanding what is the classification of sterols is fundamental to biochemistry. This guide explains their primary categorization, which is essential for grasping their diverse functions across different life forms.

According to one review, beta-sitosterol (β-sitosterol) is the most prevalent phytosterol found in human diets, commonly ingested at a rate of 200–400 mg daily. This naturally occurring compound, found in a variety of plants, is structurally similar to the body's own cholesterol and is well-regarded for its significant health benefits.

Over 250 different types of plant sterols exist, with beta-sitosterol being the most common, constituting approximately 65% of dietary intake. This essential plant compound’s structure reveals what is beta-sitosterol made of, and explains its function and similarity to, yet key difference from, cholesterol.
