Study Notes
Lipids: Fats and Oils
- Lipids are commonly known as fats and oils.
- They are a major source of energy and are vital for cell function.
- Lipids are found in both animal and plant sources.
Animal Sources of Lipids
- Meat
- Poultry
- Dairy products
Plant Sources of Lipids
- Nuts
- Seeds
- Avocado
- Olives
- Coconut
Types of Lipids
- There are three types of edible fats:
- Triglycerides (fats and oils)
- Phospholipids
- Sterols
Fat vs. Oil
- Fats are solid at room temperature and are primarily found in animal sources.
- Oils are liquid at room temperature and are primarily found in plant sources.
Triglycerides (Oils)
- Triglycerides are the most common type of fat and are comprised of 95% of all lipids.
- They are sourced from seeds, fruits, and nuts.
- Triglycerides consist of three fatty acids and a glycerol backbone.
- Oils vary in taste, color, and texture.
- They are commonly used in food preparation.
Common Vegetable Oil Sources
- Soybeans
- Rapeseed (canola oil)
- Corn
- Sunflower
- Cottonseed
- Safflower seed
Common Fruit Oil Sources
- Coconut
- Palm kernel
- Palm
- Olive
Fatty Acids
- Fatty acids are hydrocarbon chains with an even number of carbons.
- They are typically between 12-24 carbons in length.
- Medium chain fatty acids range from 6 - 10 carbons.
- Short chain fatty acids are also identified.
