Which phytosterol is specifically named as present in avocados used for guacamole?

Avocados contain the phytosterol beta-sitosterol. It is one of the plant sterols specifically identified in avocado alongside the fruit’s fats, vitamins, minerals, and carotenoids.

Phytosterols are plant compounds structurally related to cholesterol. Beta-sitosterol is especially common in plant foods and is not the same substance as cholesterol, which is primarily associated with animal tissues. That distinction explains why cholesterol is not the best answer even though the molecules belong to a related chemical family.

Avocado’s nutritional profile also includes monounsaturated and saturated fats, dietary fibre, potassium, vitamin E, vitamin K, and several B vitamins. Its carotenoids include beta-carotene, zeaxanthin, and lutein. Guacamole inherits much of this composition because raw avocado is its principal ingredient, although added ingredients change the final nutrient profile.

Lanosterol and ergosterol are also biologically important sterols, but they are not the phytosterol named in the cited avocado description. Beta-sitosterol is therefore the single canonical answer.
