Glossary Sterols

subgroup of steroids crucial for cell membrane structure

Sterols are a subgroup of steroids and an important class of organic molecules found in plants, animals, and fungi. They play a crucial role in maintaining cell membrane structure and fluidity. In humans, cholesterol is the most well-known sterol, essential for producing hormones, vitamin D, and bile acids that aid in digestion.
