Final answer:
Glucocorticoids are steroid hormones produced in the adrenal cortex that regulate metabolism and the immune system. They include cortisol, the primary stress hormone.
Step-by-step explanation:
Glucocorticoids are steroid hormones produced in the zona fasciculata of the adrenal cortex. They include the hormone cortisol, which is released in response to stress and is considered the primary stress hormone. Glucocorticoids help control the rate of metabolism of proteins, fats, and sugars. They increase the level of glucose and fatty acids in the blood, and are involved in the suppression of the immune system, acting as potent anti-inflammatory agents.
