Steroid hormones are derived from the cholesterol in the gonads and are lipid soluble molecules. These steroids are life sustaining hormones, made naturally in the body by the adrenal glands. However there are also synthetic steroid hormones that perform the same function. These steroids are known as Anabolic Steroid hormones. These steroids acts like hormones and stimulate the production of testosterone, at the same time strengthening the muscles. The hormones play a number of important physiological roles. They are a crucial substance for the proper functioning of the body.
Steroid is a class of lipids that is characterized by ‘steroid nucleus'. It is a fat soluble organic compound with an origin from plants or animals whose secretion are liberated directly to the bloodstream and transported to distant body parts.
This production and secretion of the hormones are controlled by trophic hormones which are either proteins or peptides. As per the requirements of the body steroid hormones are being made. Since the natural steroid hormones are fat soluble, they can pass through the cell membrane and can easily combine with the protein receptors.
These steroids aid events during pregnancy, suppress inflammation and also regulate mineral and sugar metabolism. The steroid hormone is to co-ordinate physiological and behavioral responses for specific biological purposes. The gonadal steroids influence the sexual differentiation of the genitalia and the brain. It determines the secondary sexual characteristics during development and sexual maturation. Thus, it contributes too the maintenance of their functional state in adulthood and to exercise control over sexual behaviors.
