Steroid and Nonsteroid Hormones

What is the main structural difference between steroid and nonsteroid hormones?

• Steroid hormones are derived from cholesterol and are lipid-soluble, while nonsteroid hormones are derived from amino acids and are water-soluble.

• Steroid hormones are derived from amino acids, while nonsteroid hormones are derived from cholesterol.

• Steroid hormones and nonsteroid hormones have the same structural composition.

• Steroid hormones are water-soluble, while nonsteroid hormones are lipid-soluble.

Which type of hormone can pass through the cell membrane to bind to intracellular receptors: steroid or nonsteroid?
