#1.3.1
Triglycerides and phospholipids are two groups of lipid.
#1.3.2
Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid.
#1.3.3
A condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond.
#1.3.4
The R-group of a fatty acid may be saturated or unsaturated.
#1.3.5
In phospholipids, one of the fatty acids of a triglyceride is substituted by a phosphate-containing group.
#1.3.6
The different properties of triglycerides and phospholipids related to their different structures.
#1.3.7
The emulsion test for lipids.
#1.3.8
Students should be able to:
- recognise, from diagrams, saturated and unsaturated fatty acids
- explain the different properties of triglycerides and phospholipids.
