Not all hormones are steroids. Steroids are a specific type of hormone that have a characteristic structure with four interconnected carbon rings. Other types of hormones, such as peptides and catecholamines, do not have this structure.
A steroid is a type of organic compound that contains a characteristic arrangement of four cycloalkanerings that are joined to each other. Examples of steroids include the dietary fat cholesterol, the sex hormones estradiol and testosterone, and the anti-inflammatory drug dexamethasone. The core of steroids is composed of twenty carbon atoms bonded together that take the form of four fused rings: threecyclohexane rings (designated as rings A, B, and C in the figure to the right) and one cyclopentane ring (the D ring). The steroids vary by the functional groups attached to this four-ring core and by the oxidation state of the rings. Sterols are special forms of steroids, with a hydroxyl group at position-3 and a skeleton derived from cholestane.
Iodine(127) is important part of thyroid hormone which help to regulate body temperature and metabolic rate. Hormones are Triiodothyronine and Thyroxine with three and four Iodine atoms respecively.

The four female hormones are lutienizing hormone, follicle stimulating hormone, estrogen, and progesterone. These fluctuate throughout their menstrual cycle.

These hormones stimulate the secretion of other hormones. Many hormones of hypothalamus are topic hormones.

Some hormones (such as steroids) are classified under lipids which actually belong to Esters group. Other hormones are proteins which belong to amine group (they are made up of amino acids).
