1. Cholesterol & Functions

Key Concepts & Definitions

  • Cholesterol: A waxy, fat-like substance found in blood and body tissues; essential for cell membrane integrity and precursor for hormones and acids.
  • Serum Cholesterol: The amount of cholesterol present in blood serum, used to assess cardiovascular risk.
  • Triglycerides (TG): Body’s storage form of fat, providing energy; circulating levels influence lipid profile.
  • Hyperlipidemia: Elevated levels of lipids (cholesterol and/or triglycerides) in blood, increasing risk for atherosclerosis.
  • LDL (Low-Density Lipoprotein): "Bad" cholesterol that deposits in arteries, promoting plaque formation.
  • HDL (High-Density Lipoprotein): "Good" cholesterol that helps remove excess cholesterol from blood.
