Cortisol hormone molecule. Computer model showing the structure of the steroid hormone cortisol (C21.H30.O5). Atoms are colour-coded (carbon: grey, hydrogen: white, and oxygen: red). Cortisol is produced by the adrenal glands, which sit on top of the kidneys. It is produced in response to stress, and increases blood pressure and blood sugar levels. It also suppresses the immune system and is used in medicine (hydrocortisone) to treat allergies, and as an anti-inflammatory.
