Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; these compounds belong to isoprenoid substances, which are generated by cyclization of triterpenes and then by internal molecular reorganization and chemical modifications.

Steroids are hormones that are naturally produced in the body. Steroid drugs are man-made and similar to the natural hormones made in the body.
