Cholesterol belongs to which class of lipid?

1. Steroids are set apart from other lipids by a fused ring structure. 2. All steroids have four linked carbon rings. 3. Cholesterol has those four rings plus a short tail, so it is a steroid. 4. It is grouped with the lipids because, like them, it is hydrophobic and insoluble in water. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 3 'Biological Macromolecules', sections 3.1-3.5_
