|LESSON 1: Basic Chemistry|
There are three types of lipids: fatty acids, triglycerides and phospholipids.
1. Fatty acids - Long carbon chains (C-C-C-C-C-C-C-C-C-C-C-C-C).
- They come in many different lengths, get many different fatty acids.
- They are non-polar, so they clump together in water (oil and water don't mix.)
- Three fatty acids linked by glycerol.
3. Phospholipid - Remove one fatty acid fromTriglyceride and add a Phosphorous
- Phospholipids organize themselves in water in unique ways.
- They are partly non-polar (long tails) and partly polar (the phosphorous end.)
- Because of this they organize together in unique ways - they form a Bilayer or a Micelle (round ball.)
- Phospholipids are used to construct cell membranes.
