Lipids
- Triglycerides and phospholipids are two types of lipids
- Triglycerides consist of one glycerol molecule and three fatty acid molecules
- An ester bond forms during a condensation reaction between glycerol and a fatty acid
- The R-group in a fatty acid can either be saturated or unsaturated
- Phospholipids have one fatty acid of a triglyceride replaced with a phosphate-containing group
- Triglycerides and phospholipids have different properties due to their different structures
- The emulsion test is used for identifying lipids
- Knowledge on structural drawing of these molecules is necessary
- Comparison between phospholipids and triglycerides is essential
- Understanding of the health implications and sources of unsaturated and saturated fats is needed.
