Types of Hormones - JSON
Hormones are chemical substances secreted by endocrine glands that act on target organs via the bloodstream. They are classified into three major categories: peptide hormones, steroid hormones, and amine hormones, with over 100 types including insulin, thyroid hormones, and adrenaline. Each plays essential roles in maintaining life, including metabolism, growth, reproduction, and stress response.
