Triglycerides and phospholipids are two groups of lipid. Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid (RCOOH) through the formation of ester bonds/three ester bonds. The of a fatty acid may be saturated or unsaturated. 0.2 weeks Describe the structure of triglycerides. Explain how triglycerides form. Recognise, from diagrams, saturated and unsaturated fatty acids.
