IBDP CORE> TOPIC 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.

Group Activity
You will work in groups of three-
Part 1- bring a lipid profile test result (from the family/relations)
Part 2- You will be given the name of a food outlet, a brand name (chocolates and deserts) and the name of disease, you have to-
You will present your work as a 5 min presentation on 13th April 2015.
Part 1- bring a lipid profile test result (from the family/relations)
- Analyse the result from the given normal values
- Give the difference between LDL and HDL cholesterol.
- Which cholesterol is harmful and which is the good cholesterol?
- Find out and the list the food items (as part of our daily diet) that increase the bad cholesterol.
- Find out and list the food items (normally consumed in daily diet) that increase good cholesterol.
Part 2- You will be given the name of a food outlet, a brand name (chocolates and deserts) and the name of disease, you have to-
- From the given food outlet, find out two food items (that is consumed by commonly) that contain highest amount of saturated fat and trans fat (either or both). Suggest food items that can be taken instead of chosen ones.
- From the given brand name find out two products that people normally consume and that contains trans fat.
- Find out if there is a relation between consumption of trans fat and saturated fatty acids with occurrence of the named disease. You need to give evidence in the form of some research conducted.
- Based on your research about the named disease, give a reflection on "do the results of the research support the health claim strongly, moderately or not all".
You will present your work as a 5 min presentation on 13th April 2015.
