Lipids

Definition

Lipids are a diverse group of hydrophobic molecules that include fats, oils, waxes, and steroids. They play key roles in energy storage, cell membrane structure, and signaling pathways.

5 Must Know Facts For Your Next Test

1. Lipids are crucial for the formation of myelin sheaths which insulate nerve cells and facilitate proper neurological function.
2. Dysregulation of lipid metabolism can contribute to chronic neurological illnesses such as multiple sclerosis and Alzheimer's disease.
3. In cardiovascular health, an imbalance of lipids can lead to conditions like atherosclerosis and coronary artery disease.
4. Essential fatty acids, such as omega-3 and omega-6, must be obtained through diet as they are vital for maintaining cardiovascular and neurological health.
5. High levels of low-density lipoprotein (LDL) cholesterol are associated with an increased risk of long-term cardiovascular diseases.
