Integrated course unit module: ORGANIC AND BIO-ORGANIC CHEMISTRY

Learning objectives

To acquire knowledge of the structure and reactivity of organic molecules, with particular attention to the biological substances. To acquire knowledge on classification and nomenclature of the organic compounds by the identification of their functional groups and , through these, on their reactivity. To learn the concepts of isomerism, conformation and stereochemistry of organic molecules and of their consequences in biological systems. To learn the principal concepts characterizing the reactivity of organic compounds in radicalic, electophilic and nucleophilic reactions. To know the functional groups and properties of some important classes of biological compounds, such as carbohydrates, triglycerides and amino acids.


General and Inorganic Chemistry
