Understandings:
Carbohydrates
Monosaccharide monomers are linked together by condensation reactions to form disaccharides and polysaccharide polymers. Glucose, ribose, fructose, galactose, deoxyribose
Sucrose, lactose and maltose should be included as examples of disaccharides produced by combining monosaccharides.
The structure of the polysaccharide starch should include amylose and amylopectin.

Application: Structure and function of cellulose and starch in plants and glycogen in humans.
Lipids:
Fatty acids can be saturated, monounsaturated or polyunsaturated. Named examples of fatty acids are not required.
Unsaturated fatty acids can be cis or trans isomers
Triglycerides are formed by condensation from three fatty acids and one glycerol.

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.

Theory of knowledge:
There are conflicting views as to the harms and benefits of fats in diets. How
do we decide between competing views?
