Steroid hormones are synthesized from cholesterol, while nonsteroid hormones are synthesized from amino acids or peptides.

Steroid hormones, being lipophilic, derive their structure from cholesterol, which is a type of lipid. This class of hormones includes cortisol, testosterone, and estrogen, among others. On the other hand, nonsteroid hormones are typically derived from proteins or peptide chains, meaning they can include hormones like insulin and glucagon that play vital roles in metabolism and homeostasis. The difference in their chemical structure influences their modes of action within the body, with steroid hormones typically interacting with nuclear receptors, while nonsteroid hormones usually bind to receptors on the cell surface, triggering secondary messenger systems.
