Which hormones are lipid-soluble?

Explanation:
Lipid-soluble hormones diffuse across the cell membrane and work by binding to intracellular receptors to change gene expression. Steroid hormones (derived from cholesterol) and thyroid hormones (T3 and T4) fit this category because they can cross the lipid bilayer and directly regulate transcription, producing longer-lasting effects. In contrast, insulin, glucagon, growth hormone, and epinephrine are water-soluble; they bind to receptors on the cell surface and trigger signaling cascades inside the cell, leading to rapid but shorter-lived responses.
