Study Notes
Lipids
- Lipids are primarily composed of fatty acids and glycerol
- They are hydrophobic and used for energy storage, hormone synthesis, and insulation/protection
- Lipids that are solid at room temperature are called fats
Types of Lipids
- Triglycerides: Used for long-term energy storage; structure includes one glycerol and three fatty acids
- Phospholipids: Important for cell membrane structure; a component of myelin sheaths in nerve cells.
- Steroids: Involved in signaling
- Sphingolipids: Found in the brain and nervous system
Fatty Acids
- Saturated Fats: Single bonds, solid at room temperature
- Unsaturated Fatty Acids: Double bonds
Trans Fats
- Primarily used to improve shelf life in food products
- Created through hydrogenation
- Lipoproteins transport lipids in the bloodstream
- Less than 1% of daily caloric intake is recommended
Cholesterol
- Vital for cell membrane fluidity and hormone synthesis
Vitamins (Lipid Soluble)
- Vitamin A: Important for vision; has antioxidant properties
- Vitamin D: Important for bone health; can be synthesized by the body
- Vitamin K: Involved in blood clotting
Vitamins (Water Soluble)
- Vitamin B1/B6: Not lipid soluble
