Study Notes
Cortisol Functions
- Cortisol plays a crucial role in glucose metabolism by stimulating the release of glucose from stored glycogen, thereby increasing blood sugar levels.
- Cortisol is mainly produced in the adrenal cortex, the outer layer of the adrenal glands, in animals.
Cortisol's Impact on Protein Synthesis
- Cortisol inhibits protein synthesis by breaking down muscle protein to provide more glucose for energy, a process known as gluconeogenesis.
Cortisol's Mechanism of Action
- Cortisol binds to glucocorticoid receptors (GRs) inside the cell, which subsequently impact gene expression by regulating transcription.
Cortisol as a Medication
- Cortisol is also known as hydrocortisone when used as a medication, often to treat conditions such as Addison's disease or adrenal insufficiency.
