Understandings
2.3.U1 Monosaccharide monomers are linked together by condensation reactions to form disaccharides and polysaccharide polymers
2.3.U2 Fatty acids can be saturated, monounsaturated or polyunsaturated
2.3.U3 Unsaturated fatty acids can be cis or trans isomers
2.3.U4 Triglycerides are formed by condensation form three fatty acids and one glycerol
Applications
2.3.A1 Structure and function of cellulose and starch in plants and glycogen in humans
2.3.A2 Scientific evidence for health risks or trans-fats and saturated fats
2.3.A3 Lipids are more suitable for long-term energy storage in humans than carbohydrates
2.3.A4 Evaluation of evidence and the methods used to obtain evidence for health claims made about lipids
Skills
2.3.S1 Use of molecular visualization software to compare cellulose, starch and glycogen
2.3.S2 Determination of body mass index by calculation or use of a nomogram
Nature of science
o Evaluating claims: health claims made about lipids need to be assessed
