Cholesterol Metabolism

Definition

Cholesterol metabolism is the process by which the body breaks down, synthesizes, and regulates cholesterol levels to ensure proper cellular function and hormonal balance.

Scientific / Technical Definition

Cholesterol metabolism involves the absorption, synthesis, and catabolism of cholesterol, a vital lipid molecule essential for cell membrane structure, bile acid formation, and steroid hormone production. The liver plays a central role in balancing cholesterol levels through synthesis and removal via bile excretion, while lipoproteins transport cholesterol throughout the body.

Benefits

• Essential for building and maintaining cell membranes
• Necessary for the production of steroid hormones
• Plays a role in the synthesis of vitamin D
• Important for the production of bile acids, which aid in digestion

Examples

• Eggs
• Dairy products
• Meat
• Poultry
• Fish

Additional Information

• Effects: Cholesterol metabolism affects cardiovascular health, as imbalances can lead to the accumulation of plaques in arteries, increasing the risk of heart disease.
