steroïde

Steroid refers to a class of organic compounds that have a specific arrangement of four fused carbon rings. This core structure, known as the steroid nucleus, is found in various biologically important molecules. Cholesterol is a well-known example of a steroid, playing a crucial role in cell membranes and serving as a precursor for other steroid compounds.

Hormones are another significant group of steroids. The adrenal glands produce corticosteroids like cortisol, which regulate metabolism and immune responses, and aldosterone, which controls blood pressure. Sex hormones, such as testosterone and estrogen, are also steroids and are vital for the development and function of reproductive systems.

Synthetic steroids, often referred to as anabolic-androgenic steroids (AAS), are chemically engineered versions of natural hormones. They are sometimes prescribed for medical conditions like muscle wasting diseases or delayed puberty. However, AAS are also misused to enhance athletic performance and muscle growth. This misuse can lead to serious health consequences, including cardiovascular problems, liver damage, and psychological effects. The use of anabolic steroids without medical supervision is illegal in many countries and is prohibited by most sports organizations.
