They cross the cell membrane and bind to some receptor in the cytosol, causing it to translocate to the nucleus where it can regulate genetic events.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Cholesterol is a component of the phospholipid bilayer and plays a role in the structure and function of membranes.
