State
Hormones divide into three chemical classes: lipid-derived steroid hormones, amino acid-derived hormones, and peptide hormones, distinguished chiefly by whether they can diffuse across a plasma membrane.
Show
Testosterone, a steroid hormone, diffuses directly across a target cell's membrane; insulin, a peptide hormone, cannot.
Watch for
A hormone's chemical class predicts its receptor location, not its potency — small amino acid-derived hormones can have large effects.
