Integrated course unit module: CHEMICAL BASICS AND MECHANISMS OF RISK FACTORS

Learning objectives

The first section objective is knowledge and understanding of chemical properties of the principal molecules of biological interest. In the second section the objective becomes the knowledge of structural, functional and relational features of biomolecules. These skills will be functional for understanding the fundamentals of enzymology and metabolic processes.

Course unit content

After a brief introduction to the basic principles of Organic Chemistry, the main molecules of biological systems will be presented: carbohydrates, lipids, proteins and nucleic acids, and ATP as energy transporter (Structural Biochemistry).
In the second section main subject will be Metabolic Biochemistry with particular emphasis on bioenergetics, red-ox biological reactions, and cell metabolism.

Teaching methods

Frontal lessons will be aided by presentations and videos, valuing the molecular approach and the overview of metabolism; interactive web sites will be used when possible.

Assessment methods and criteria

The oral test will deal with Structural and General Biochemistry; knowledge of enzymatic catalysis, bioenergetics and integration of metabolism will improve the grade.
