2/ Cholesterol is an organic molecule that is essential for all animal life.
3/ Each cell of our body is able to synthesize cholesterol by way of a complex process which begins with HMG-CoA reductase (the target of statins.
4/ About half of this excreted cholesterol is reabsorbed back by the small intestine back into the bloodstream.
5/ The main function of lipoproteins is to transport triglycerides to cells. Cholesterol itself is a secondary passenger.
6/ In most people the cholesterol content within LDL particles is fairly proportional to the number of LDL particles.
7/ The Friedewald equation (mg/dL):
LDL-C mg/dL = Total cholesterol – (HDL-C + VLDL-C*)
*VLDL-C is calculated as Triglycerides/5
LDL-C mg/dL = Total cholesterol – (HDL-C + VLDL-C*)
*VLDL-C is calculated as Triglycerides/5
8/ The LDL particle causes plaque to develop in the artery, not the cholesterol.
9/ Those with higher heart disease risk and those with evidence of heart disease tend to have more of the particles that are smaller and denser (sdLDL)
10/ Things that have been associated with high circulating small dense LDL-C (sdLDL-C) levels:
- Hypertriglyceridemia
- Increased dietary carbohydrates
- Insulin resistance
- Low HDL-C concentrations
- Obesity
- Systemic inflammation
- Metabolic syndrome
- Genetics

11/ Apolipoproteins are proteins that are associated with lipoproteins – they have four major roles
o Provide structural support
o Act as a ligand for receptors
o Guide the formation of lipoproteins
o Act as activators or inhibitors of certain enzymes
