Quizplus · Accepted Answer

Steroids are characterized by a core structure of four linked carbon rings. This structure is distinct from the other options listed, which have different defining features: phospholipids have a glycerol backbone with fatty acid chains and a phosphate group, nucleotides consist of a sugar, phosphate group, and nitrogenous base, fatty acids are long hydrocarbon chains with a carboxyl group at one end, and amino acids have an amino group, a carboxyl group, and a unique side chain attached to a central carbon.
