Study Notes
Lipid Structures and Types
- Triglycerides are composed of three fatty acids attached to glycerol.
- Saturated fats are solid at room temperature and can be hydrogenated.
- Unsaturated fats remain liquid at room temperature.
Cell Membrane Composition
- The cell membrane is primarily made of phospholipids, organized into a lipid bilayer.
Special Lipid Classes
- Steroids are lipids characterized by a multiple ring structure.
- Bile is crucial for emulsifying fats, while lipases are enzymes that digest fats.
Lipoproteins
- Chylomicrons represent the largest and least dense lipoproteins, produced in the small intestine.
Essential Fatty Acids
- Essential fatty acids must be supplied through the diet.
- Linoleic acid is the precursor for omega-6 fatty acid family.
- Hormones secreted by adipose tissue are known as adipokines.
- Eicosanoids are hormone-like compounds that exert localized effects.
- Omega-3 fatty acids develop from linolenic acid.
Cardiovascular Health
- Elevated levels of LDL cholesterol are significant risk factors for cardiovascular disease (CVD).
- A desirable total cholesterol level is crucial for maintaining heart health.
