What are Lipids?Sketch a drawing of a fatty acid
Outcomes
3: Identify from the structures a range of biological
molecules.
5: Explain the function of a range of biological molecules in both animals and plants.
7: Evaluate the biological importance of hydrolysis and
condensation reactions in biological molecules.
Key terms: triglycerides, lipids, phospholipids
What are Lipids?Objectives
Know fatty acids can be saturated, monounsaturated
or polysaturated.
Understand fatty acids can be cis or trans isomers.

What are Lipids?Answer the past paper
question on lipids
1. (a) margarine / sunflower seeds / vegetable oil / peanuts / nuts,etc. (no animal products) 1(b) energy storage / energy supply;hormone production;cushioning / protection;insulation;(constituent of) membranes;cell respiration;myelin sheath; 2 max (c) saturated fatty acids cause high cholesterol;atherosclerosis / narrowing of (lumen of) arteries;CHD / formation of clots / heart attack / heart failure / thrombosis / stroke;hypertension / high blood pressure;obesity / overweight;which is linked to diabetes;although there are also genetic factors / some countries eat a lot of fats and have low CHD; 4 max
