Hormon steroid pada umumnya disintesa dari [[kolesterol]] di dalam [[gonad]] dan [[kelenjar adrenal]]. Bentuk dari hormon ini, biasanya adalah [[lipid]], bukan [[protein|peptida]], dan mempunyai kurir khusus berbentuk [[globulin]]. Hormon steroid biasanya bersifat [[katabolisme]].
<!--
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, and then quite easily combine with a protein receptor which may be nuclear or cytosolic depending on the steroid hormone, to bring about changes within the cell. 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.
