Verified step by step guidance

Understand the classification of hormones based on their solubility: Hormones can be classified as either water-soluble or lipid-soluble. Water-soluble hormones include peptide hormones and amino acid-derived hormones, while lipid-soluble hormones include steroid hormones and thyroid hormones.

Recognize the chemical nature of steroid hormones: Steroid hormones are derived from cholesterol, which is a lipid. This makes them lipid-soluble, allowing them to pass through cell membranes easily.

Identify the characteristics of thyroid hormones: Thyroid hormones, although derived from amino acids, are unique because they are lipid-soluble. This is due to their iodine content and structural configuration, which allows them to diffuse through cell membranes.

Compare the solubility of different hormone types: Peptide hormones and amino acid-derived hormones are generally water-soluble, meaning they cannot pass through the lipid bilayer of cell membranes without a receptor. In contrast, lipid-soluble hormones like steroid and thyroid hormones can diffuse directly through the cell membrane.

Conclude the classification: Based on the solubility characteristics, steroid hormones and thyroid hormones are classified as lipid-soluble hormones, which distinguishes them from peptide and amino acid-derived hormones.
