Question: 1 / 400

What is the main structural characteristic of sterols?

A ring-like structure that is highly hydrophobic and structurally rigid

Sterols are a type of lipid with a unique ring-like structure that is highly hydrophobic and structurally rigid. This structure is what gives sterols their characteristic properties and functions, such as regulating membrane fluidity and serving as precursors for hormone synthesis. Linear chains of unsaturated fatty acids (option B) do not possess this unique ring structure and do not have the same functions as sterols. Single-stranded DNA (option C) and double-helical structure typical of proteins (option D) refer to completely different biomolecules and are not considered structural characteristics of sterols. Therefore, the main structural characteristic of sterols is a ring-like structure that is highly hydrophobic and structurally rigid.
