검증된 단계별 안내1
Identify the structure of each hormone listed: Testosterone, Cortisol, Estrogen, and Insulin.
Understand that steroid-based hormones are derived from cholesterol and have a characteristic four-ring structure known as the steroid nucleus.
Examine the chemical structure of Testosterone, Cortisol, and Estrogen to confirm they all contain the steroid nucleus.
Recognize that Insulin is a peptide hormone, which means it is composed of amino acids and does not have the steroid nucleus.
Conclude that Insulin, lacking the steroid nucleus, is not a steroid-based hormone, unlike the others listed.
