Study Notes
Lipid Classification
- Simple lipids: Composed of fatty acids and alcohols, including triglycerides (oils and fats) and waxes.
- Compound lipids: Complexed with other components; includes phospholipids, glycolipids, and lipoproteins.
- Derived lipids: Includes fatty acids, steroids, and fat-soluble vitamins.
Complex Lipids
- Formed by lipids bonded with other groups:
- Phospholipids: Contain phosphate groups.
- Glycolipids: Contain carbohydrate moieties.
- Lipoproteins: Contain protein moieties.
- Sulpholipids: Contain sulfur groups.
- Aminolipids: Contain amino groups.
Phospholipids
- Two types:
- Glycerophospholipid: Made from glycerol.
- Sphingophospholipid: Made from sphingosine.
- Amphipathic nature due to hydrophilic (water-attracting) and hydrophobic (water-repelling) parts.
- Phosphate group may be attached to nitrogenous bases like choline, serine, or inositol.
Types of Glycero Phospholipids
- Phosphatidic Acid: Simplest phospholipid, functioning as an intermediate in triglyceride and lecithin synthesis.
- Lecithin (Phosphatidyl Choline): Vital for forming cell walls and membranes.
- Cardiolipin (Di Phosphatidyl Glycerol): Important for mitochondrial structure and function.
Other Key Lipids
- Sialic Acid: A component of gangliosides; enhances cell recognition and signaling.
- Ceramide: Key component of sphingolipids, present in various membranes (notable in nervous system).
- Sulpholipids: Typically contain sulfated carbohydrates, adding to their structural properties.
Chemical Groups in Phospholipids
- Phosphatidylserine: Functions in cellular signaling and apoptosis.
- Phosphatidylinositol: Plays a role in cell signaling pathways.
Functionality Overview
- Phospholipids are crucial for forming cellular membranes, providing structure and fluidity.
- Sphingomyelin forms protective sheaths around neurons, essential for proper electrical signal conduction.
- Complex lipids assist in various metabolic processes and play significant roles in biological membranes.
