This 30-slide powerpoint presentation covers 'Topic 2.3 - Carbohydrates & Lipids' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into 3 sections:
A - Carbohydrates
B - Lipids
C - Health
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Monosaccharide monomers are linked together by condensation reactions to form disaccharides and polysaccharide polymers.
U2: Fatty acids can be saturated, monounsaturated or polyunsaturated.
U3: Unsaturated fatty acids can be cis or trans isomers.
U4: Triglycerides are formed by condensation from three fatty acids and one glycerol.
A1: Structure and function of cellulose and starch in plants and glycogen in humans.
A2: Scientific evidence for health risks of trans fats and saturated fatty acids.
A3: Lipids are more suitable for long-term energy storage in humans than carbohydrates.
A4: Evaluation of evidence and the methods used to obtain the evidence for health claims made about lipids.
S1: Use of molecular visualization software to compare cellulose, starch and glycogen.
S2: Determination of body mass index by calculation or use of a nomogram.
