Verified step by step guidance

Step 1: Begin by understanding the structure and origin of cholesterol. Cholesterol is a lipid molecule that serves as a precursor for the synthesis of certain types of hormones.

Step 2: Learn about the classification of hormones. Hormones are broadly categorized into groups such as amino acid-derived hormones, peptide hormones, eicosanoid hormones, and steroid hormones.

Step 3: Examine the synthesis pathways of each hormone group. Amino acid-derived hormones are synthesized from amino acids like tyrosine, peptide hormones are composed of chains of amino acids, and eicosanoid hormones are derived from fatty acids. Steroid hormones, however, are synthesized from cholesterol.

Step 4: Understand the chemical properties of steroid hormones. These hormones are lipophilic (fat-soluble) and include examples like cortisol, testosterone, and estrogen. Their synthesis involves enzymatic modifications of the cholesterol molecule.

Step 5: Conclude that steroid hormones are the group synthesized from cholesterol, distinguishing them from other hormone groups based on their origin and chemical structure.
