2.3 Carbohydrates and lipids
Understandings:
• Monosaccharide monomers are linked together by condensation reactions to form disaccharides and polysaccharide polymers.
• Fatty acids can be saturated, monounsaturated or polyunsaturated.
• Unsaturated fatty acids can be cis or trans isomers.
• Triglycerides are formed by condensation from three fatty acids and one glycerol.
Applications and skills:
• Application: Structure and function of cellulose and starch in plants and glycogen in humans.
• Application: Scientific evidence for health risks of trans fats and saturated fatty acids.
• Application: Lipids are more suitable for long-term energy storage in humans than carbohydrates.
• Application: Evaluation of evidence and the methods used to obtain the evidence for health claims made about lipids.
• Skill: Use of molecular visualization software to compare cellulose, starch and glycogen.
• Skill: Determination of body mass index by calculation or use of a nomogram.
