ApoA1
ApoA1 (apolipoprotein A1) is the main protein in HDL particles, which carry cholesterol back to the liver.
ApoA1 (apolipoprotein A1) is the main protein in HDL particles. HDL carries cholesterol from the tissues back to the liver, and ApoA1 is what lets the particle do that job. Measuring ApoA1 adds detail to the HDL value in the lipid panel.
Regular physical activity tends to raise ApoA1, while smoking, a diet high in sugar and refined carbohydrates, and higher body weight tend to lower it. Alcohol raises it, and inherited factors play a part.
