High blood cholesterol increases the risk of CVD

Includes:

-cholesterol

 -high density and low density lipoproteins

-saturated and polysaturated fats

I got my information from the 'CGP AS Level Biology Revsion guide, ISBN: 978 1 84762 121 4'

  • HIGH BLOOD CHOLESTEROL INCREASES THE RISK OF CVD
    • Cholesterol is a lipid
      • Needed for the body to function normally
      • Cholesterol needs to attach to a protein to move around the body = LIPOPROTEIN
    • TWO TYPES OF LIPOPROTEINS
      • HIGH DENSITY LIPOPROTEIN (HDL)
        • Mainly made out of protein
        • Transport cholesterol from body tissues to the liver (excreted/recycled)
        • Function; reduce blood cholesterol when the level is too high
      • LOW DENSITY LIPOPROTEIN (LDL)
        • Mainly lipid
        • Transport cholesterol from the liver to the blood where they circulate until they are needed by cells
        • Function; increase blood cholesterol when level is too low
    • High total blood cholesterol level & high LDL level = increase risk of CVD
      • Diet in high saturated fat raises LDL level
        • More cholesterol is transported to the blood
          • Increases total blood cholesterol & increases the risk of CVD
    • Diet high in polyunsaturated fat raises HDL level
      • Cholesterol is transported from the blood to the liver
        • Decreases total blood cholesterol and decreases the risk of CVD
