Forensic Chemistry > 2. Analysis of Organic Material Can Distinguish Plant And Animal Material >
Analysis of organic material can distinguish plant and animal material
Students learn to:
- identify that carbohydrates are composed of carbon, hydrogen and oxygen according to the formula :Cx (H2O)y
- identify glucose as a monomer and describe the condensation reactions which produce:
– sucrose as an example of a dissacharide
– polysaccharides including glycogen, starch and cellulose - describe the chemical difference between reducing and non-reducing sugars
- distinguish between plant and animal carbohydrates’ composition in terms of the presence of:
– cellulose
– starch
– glycogen
Students:
- choose equipment, plan and perform a first-hand investigation to carry out a series of distinguishing tests for the carbohydrates:
– reducing and non-reducing sugars
– starch - use available evidence and perform first-hand investigations using molecular model kits, computer simulations or other multimedia resources to compare the structures of organic compounds including:
– monosaccharides
– starch
