🧠 2️⃣ Mnemonics
Mnemonic Title:
Main Lipoprotein Functions
Mnemonic Word: “Carry Very Large Happiness”
Meaning:
- Carry = Chylomicrons → Carry dietary TG
- Very = VLDL → Very rich in TG
- Large = LDL → Large cholesterol carrier
- Happiness = HDL → Helpful/protective lipoprotein
Mnemonic Title:
Atherogenic vs Protective
Mnemonic Word: “Lousy LDL, Healthy HDL”
Meaning:
- LDL → Plaque formation
- HDL → Removes cholesterol
Mnemonic Title:
Important Apolipoproteins
Mnemonic Word: “Boys Carry Energy”
Meaning:
- B-48 → Chylomicrons
- C-II → Activates LPL
- E → Hepatic remnant uptake
📋 3️⃣ Memory Tables
Table 1 — Lipoprotein Comparison
| Lipoprotein | Main Function | Main Lipid | Important Apo |
|---|---|---|---|
| Chylomicrons | Dietary TG transport | TG | Apo B-48 |
| VLDL | Endogenous TG transport | TG | Apo B-100 |
| LDL | Cholesterol delivery | Cholesterol | Apo B-100 |
| HDL | Reverse cholesterol transport | Cholesterol | Apo A-I |
Table 2 — Clinical Associations
| Condition | Main Defect |
|---|---|
| Familial hypercholesterolemia | LDL receptor defect |
| Type I hyperlipoproteinemia | LPL deficiency |
| Atherosclerosis | Increased LDL |
| Metabolic syndrome | High TG + low HDL |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
- Chylomicrons carry dietary triglycerides.
- VLDL carries endogenous triglycerides.
- LDL delivers cholesterol to tissues.
- HDL removes cholesterol from tissues.
- Apo C-II activates lipoprotein lipase.
- Apo B-100 binds LDL receptors.
- Oxidized LDL forms foam cells.
- LDL promotes atherosclerosis.
- HDL is cardioprotective.
- Severe hypertriglyceridemia may cause pancreatitis.
- Statins reduce cholesterol synthesis.
- Familial hypercholesterolemia causes premature CAD.
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Familial hypercholesterolemia → LDL receptor defect.
Clinical Hook:
LPL deficiency → Severe hypertriglyceridemia + pancreatitis.
Clinical Hook:
Low HDL → Increased atherosclerosis risk.
Clinical Hook:
Diabetes mellitus → Increased VLDL and triglycerides.
Clinical Hook:
Oxidized LDL → Foam cell formation.
