I - Isoprenoids or terpenes are formed by the union of isoprene molecules and are responsible for the coloration of flowers and fruits.
II - Steroids are very complex molecules formed by cyclic carbon rings and are fundamental for the structure of cell membranes.
III - Unsaponifiable lipids are obtained from triglycerides and are responsible for the formation of soap.
IV - An example of an isoprenoid is β-carotene, which is a vegetable pigment that participates in photosynthesis and colors fruits.

The correct statements regarding unsaponifiable lipids are:
II - Steroids are very complex molecules formed by cyclic carbon rings and are fundamental for the structure of cell membranes.
IV - An example of an isoprenoid is β-carotene, which is a vegetable pigment that participates in photosynthesis and colors fruits.
Unsaponifiable lipids cannot be hydrolyzed or saponified to produce soap. Instead, they include lipids like steroids and terpenes. Steroids, with their cyclic carbon ring structure, are indeed essential for the structure of cell membranes. Isoprenoids or terpenes, on the other hand, are formed by the union of isoprene molecules and can contribute to the coloration of flowers and fruits, with β-carotene being an example of an isoprenoid.
