No, steroid hormones are not proteins. They are a type of lipid molecule that are derived from cholesterol.
Cholesterol is the most important steroid molecule because it serves as a precursor for the synthesis of other essential steroids in the body, including hormones like cortisol, estrogen, and testosterone. Additionally, cholesterol is a key component of cell membranes and plays a crucial role in maintaining cell structure and function.
Cholesterol

One example is the steroid hormone cortisol. Cortisol can diffuse across the cell membrane and bind to intracellular receptors called glucocorticoid receptors. This complex can then enter the nucleus and regulate the expression of specific genes, turning them on or off.
is a stabilizing component of the plasma membranes and is the parent molecule of steroid hormonesJordanM.
