Steroids

Steroids are a class of organic compounds characterized by a specific molecular structure consisting of four fused rings: three six-membered rings and one five-membered ring. This structure is known as a steroid nucleus or steroid skeleton. Steroids are classified into different groups based on their specific chemical modifications and biological functions. They are widely distributed in nature and play essential roles in various physiological processes. In animals, steroids serve as hormones that regulate metabolism, inflammation, immune response, and reproductive functions. Examples of steroid hormones include cortisol, estrogen, testosterone, and progesterone. In addition to their hormonal roles, steroids are also used therapeutically in medicine to treat inflammatory conditions, autoimmune diseases, hormonal deficiencies, and certain types of cancer. They are also misused as performance-enhancing drugs due to their ability to promote muscle growth and endurance.
