Steroids are a class of organic compounds that are derived from cholesterol. They are hydrophobic in nature and can easily pass through the cell membrane to bind to intracellular receptors. They do not initiate synthesis of the second messenger system within their target cells. Epinephrine is not a steroid, but a hormone derived from the amino acid tyrosine.
