Steroid hormones are important bioactive molecules that play a critical role in regulating various physiological functions in the body. These hormones are synthesized from cholesterol and are classified as lipids due to their hydrophobic nature. Steroid hormones are responsible for numerous functions in the human body, including regulating metabolism, reproduction, and immune function. Synonyms for the term steroid hormone include sex hormones, corticosteroids, and anabolic steroids. While these hormones are known for their benefits, they can also have negative side effects when abused or taken in excess. Therefore, it is essential to use steroid hormones under the guidance of a medical professional.
