What is 24S-Hydroxycholesterol? This molecule, also known as cerebrosterol, plays a crucial role in brain health. It's a derivative of cholesterol, produced mainly in the brain by neurons. Unlike cholesterol, which can't cross the blood-brain barrier, 24S-Hydroxycholesterol can. This ability allows it to help regulate cholesterol levels in the brain by transporting excess cholesterol to the liver for excretion. Additionally, it has been linked to various neurological conditions, including Alzheimer's disease and multiple sclerosis. Understanding this molecule can provide insights into brain function and potential treatments for neurological disorders. Dive into these 30 intriguing facts about 24S-Hydroxycholesterol to learn more!
