Study Notes
Lipid Functions and Classification
- Triglycerides (Triacylglycerols) primarily serve as energy storage in fat cells (adipocytes).
- Membrane lipids primarily function as structural components of cell membranes, maintaining the cell's integrity and regulating the passage of materials.
- Saturated fatty acids have no double bonds in their carbon chain.
- Emulsification lipids, such as bile salts, facilitate the digestion of fats by breaking them down into smaller particles.
- Steroid hormones (e.g., cholesterol, estrogen, and testosterone) and eicosanoids (e.g., prostaglandins) are classified as Steroids.
- Triacylglycerols (Triglycerides) are classified as Neutral Lipids.
- Saturated fatty acids contain no double bonds in their carbon chain.
- In the body, lipids are stored as energy in adipose tissue (fat cells).
- Emulsification lipids, such as bile salts, are involved in emulsification, facilitating the digestion of fats.
- Waxes, such as beeswax and lanolin, are classified as lipids and serve as biological waxes, providing protection and water repellency.
