Verified step by step guidance

Understand the classification of hormones: Hormones can be classified into three main types based on their chemical structure: steroid hormones, peptide hormones, and amino acid-derived hormones.

Identify the characteristics of amino acid-derived hormones: These hormones are synthesized from amino acids, primarily tyrosine and tryptophan. They include catecholamines (like epinephrine and norepinephrine) and thyroid hormones.

Examine each hormone option: Aldosterone is a steroid hormone derived from cholesterol, insulin is a peptide hormone composed of amino acids, and cortisol is also a steroid hormone.

Recognize epinephrine as an amino acid-derived hormone: Epinephrine is synthesized from the amino acid tyrosine and is classified as a catecholamine, which is a type of amino acid-derived hormone.

Conclude that epinephrine is the correct answer: Based on the chemical structure and synthesis pathway, epinephrine fits the classification of an amino acid-derived hormone.
