Steroid

hormones Steroid hormones are one of the most important classes of hormones in the human body. They are a group of naturally-occurring molecules which are responsible for a range of physiological processes, such as growth, metabolism, and sexual development. Steroid hormones are secreted by the adrenal glands, ovaries, and testes, and circulate in the body attached to proteins. When they bind to specific target cells in the body, they are able to interact with the cell's DNA to regulate the expression of genes related to their action. As such, steroid hormones are integral to normal functioning of the body, particularly in the areas of growth, metabolism, and reproduction. They are also used to treat certain diseases, such as adrenal insufficiency and in cancer treatments.
