Cortisol is a steroid hormone, specifically a glucocorticoid.
What is Cortisol?
Cortisol is produced in the adrenal cortex, which is part of the adrenal glands located above the kidneys. Once synthesized, cortisol is released into the bloodstream, where it travels throughout the body to exert its effects on various organs and tissues.

Steroid Hormone: As a steroid hormone, cortisol is derived from cholesterol and can easily pass through cell membranes. This allows it to interact directly with receptors inside cells, influencing gene expression.
-
Glucocorticoid: Cortisol is classified as a glucocorticoid because of its significant impact on glucose metabolism. It plays a crucial role in regulating blood sugar levels.
