Study Notes
Energy Content and Composition of Fats
- 1 gram of fat contains approximately 9 calories of energy, making it a dense energy source.
- Saturated fat features carbon atoms that are bonded to the maximum number of hydrogen atoms, specifically 2 hydrogen atoms for each carbon atom.
Types of Fatty Acids
- Unsaturated fatty acids have a bent hydrocarbon chain due to one or more double bonds between carbon atoms.
Lipid Transport
- Lipids are transported in the blood as part of lipoproteins, which are complexes of lipids and proteins, enabling their solubility in blood.
Comparison with Carbohydrates
- Fats serve as a richer energy source compared to carbohydrates, providing more energy per gram.
Structure of Fatty Acids
- Saturated fatty acids are typically solid at room temperature due to their straight chains that allow tight packing.
Function and Sources of Lipids
- The majority of dietary lipids are found in oils, dairy products, meats, and nuts, contributing essential fatty acids and energy.
- Lipids play crucial roles in the body, including energy storage, insulation, cellular structure, and hormone production.
Role of Lipoproteins
- Lipoproteins facilitate the transportation of lipids in the bloodstream, aiding in their delivery to various tissues and organs.
