Study Notes
Lipids Overview
- Lipids are diverse molecules that are hydrophobic or amphipathic, playing crucial roles in biological systems.
- They serve as energy stores, structural components of cell membranes, and signaling molecules.
Complex Lipids
- Complex lipids are categorized into two main groups:
- Phospholipids: Composed of glycerol, fatty acids, and a phosphate group; essential for forming cell membranes.
- Glycolipids: Contain carbohydrate groups attached to lipids, important for cell recognition and signaling.
Composition of Solid Fats
- Solid fats primarily consist of saturated fatty acids, which contribute to their stable structure at room temperature.
- Saturated fats are typically found in animal fats and some tropical oils, leading to higher melting points.
Structures of Fats
- Fats are mainly triglycerides, formed by glycerol bonded to three fatty acids.
- Fatty acids can be saturated or unsaturated, affecting the physical properties of the fat.
Components of Cell Membranes
- Key components of cell membranes include phospholipids and cholesterol, providing fluidity and structural integrity.
- Proteins embedded in the membrane assist in transport and communication with the environment.
