The natural steroid hormones are generally synthesized from [[cholesterol]] in the [[gonad]]s and [[adrenal gland]]s. These forms of hormones are [[lipid]]s. They can pass through the cell membrane as they are fat-soluble,<ref name="HeffnerSchust2010">{{cite book|author1=Linda J. Heffner|author2=Danny J.

Steroid hormones are generally carried in the blood, bound to specific carrier [[protein]]s such as [[sex hormone-binding globulin]] or [[corticosteroid-binding globulin]]. Further conversions and catabolism occurs in the liver, in other "peripheral" tissues, and in the target tissues.
