SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

1. Aspects of Biochemistry (cont’d)

Students should be able to:

1.5. discuss how the molecular Molecular structure:
structure of starch, types of bonds; chain and
glycogen and cellulose ring structure where
relate to their functions in appropriate; 3D nature;
living organisms; hydrolysis and
condensation reactions;
relate structure to
properties.

1.6. describe the molecular Without going into detail,
structure of a triglyceride the student should be
and its role as a source made aware of the
of energy; relationship between
triglycerides and obesity.

1.7. describe the structure Relate structure to
of phospholipids and properties and hence to
their role in membrane function.

1.8. describe the generalised
structure of an amino acid,
and the formation and
breakage of a peptide
bond;

1.9. carry out tests for Benedict’s test, KI/I2 test, Investigate and compare
reducing and non- emulsion test, Biuret test. quantitatively reducing
