                                The human body produces over 200 different types of steroid metabolites, but among them, the C18 hormones play a particularly significant role in health and development. This critical class of steroids is distinguished by its 18-carbon skeleton and distinct aromatic A-ring, with estrogens being the most well-known examples.
