Verified step by step guidance

Understand the question: The problem asks which chemical class of hormones is derived from cholesterol. Cholesterol is a precursor molecule for certain types of hormones, so identifying the correct class requires knowledge of hormone biochemistry.

Recall the major classes of hormones: Hormones are categorized into peptide hormones, eicosanoid hormones, amino acid-derived hormones, and steroid hormones. Each class has distinct chemical properties and biosynthetic pathways.

Focus on steroid hormones: Steroid hormones are synthesized from cholesterol. Cholesterol undergoes enzymatic modifications in the mitochondria and smooth endoplasmic reticulum to form steroid hormones such as cortisol, aldosterone, and sex hormones (e.g., estrogen, testosterone).

Eliminate other options: Peptide hormones are composed of amino acid chains and are not derived from cholesterol. Eicosanoid hormones are derived from fatty acids like arachidonic acid, not cholesterol. Amino acid-derived hormones are synthesized from individual amino acids like tyrosine or tryptophan, not cholesterol.

Conclude that steroid hormones are the correct answer: Based on the biosynthetic pathway and chemical origin, steroid hormones are the class derived from cholesterol.
