Where in the body is cholesterol found?

Cholesterol is a type of lipid that is found in all cells of the body, and it plays several critical roles, particularly in forming cell membranes. Cell membranes require cholesterol to maintain their structure and fluidity, which helps facilitate communication between cells and supports various cellular functions. Furthermore, cholesterol is a precursor for the synthesis of important biomolecules, including steroid hormones and bile acids.

This comprehensive presence of cholesterol is essential for maintaining the integrity and functionality of cells throughout the body. While it can be synthesized by the liver and is also transported in the blood, its distribution is not limited to these areas. Cholesterol is integral to virtually all cell types, which is why its presence is noted particularly in cell membranes.
