Students will be able to
- describe how calorimetry can be used to measure energy contained in food,
- carry out the following tests on food samples, stating observations for positive results: Benedict’s test for reducing sugars (glucose), iodine test for starch, Biuret reagent for proteins, emulsion test for fats, and Sudan IV test for lipids,
- describe the structure of carbohydrates, for example, starch, as a polymer made up of simple sugar monomers,
- describe the structure of a protein as a polymer made up of amino acid monomers,
- recall that lipids are large molecules made up of glycerol and fatty acid molecules.
Students should already be familiar with
- the fact that key components of the human diet include proteins, fats, and carbohydrates.
Students will not cover
- condensation/hydrolysis reactions,
- bonds formed between the monomers in biological molecules.
