Verified step by step guidance

Step 1: Begin by understanding the classification of hormones based on their chemical structure. Hormones can be broadly categorized into amino acid-derived hormones, peptide hormones, glycoprotein hormones, and steroid hormones.

Step 2: Recall that steroid hormones are derived from lipids, specifically cholesterol. This distinguishes them from other hormone types, which are derived from amino acids or proteins.

Step 3: Review examples of steroid hormones, such as cortisol, testosterone, and estrogen, which are synthesized in the adrenal glands and gonads. These hormones are lipid-soluble and can pass through cell membranes to bind to intracellular receptors.

Step 4: Compare steroid hormones to other hormone types mentioned in the problem. Amino acid-derived hormones (e.g., epinephrine) are synthesized from single amino acids, glycoprotein hormones (e.g., follicle-stimulating hormone) are proteins with carbohydrate groups attached, and peptide hormones (e.g., insulin) are short chains of amino acids.

Step 5: Conclude that hormones made from lipids are categorized as steroid hormones, as they are structurally and functionally distinct from the other types listed.
