ApoA-I (Apolipoprotein A-I)

ApoA-I, or Apolipoprotein A-I, is the main protein component of HDL cholesterol, often called "good" cholesterol. It plays a key role in removing excess cholesterol from the bloodstream and cells, helping to transport it to the liver for disposal or recycling. This process helps protect against the buildup of fatty deposits in arteries, reducing the risk of heart disease. ApoA-I also helps activate enzymes involved in cholesterol metabolism, maintaining healthy blood vessel function. In essence, ApoA-I is vital for helping keep blood cholesterol levels balanced and supporting cardiovascular health.
