Plants contain a variety of sterols like stigmasterol, ergosterol, sitosterol etc., which very closely resemble cholesterol. These plant sterols are referred as :

Plants contain various sterols such as stigmasterol, ergosterol, and sitosterol, which are collectively referred to as phytosterols [2]. These natural plant compounds belong to the triterpene family and are structurally very similar to cholesterol, which is the primary zoosterol found in animals [1]. Phytosterols are essential components of plant cell membranes and are found in high concentrations in vegetable oils and oilseeds [2]. While they resemble cholesterol, they differ slightly in their carbon side chains or the presence of double bonds [2]. In contrast, calciferols (including ergocalciferol or Vitamin D2) are vitamers of Vitamin D produced through the irradiation of sterols like ergosterol [3]. Lumisterol is a stereoisomer produced in the skin via the photochemical transformation of pre-vitamin D3 during UV exposure [4]. Therefore, the general term for these plant-derived sterols is phytosterols.
