Good knowledge on General and Organic Chemistry

The aims include: the knowledge of the structure and function of the major macromolecules of biological interest with particular attention to the structural-functional relationships; the understanding of the metabolic processes and energetic pathways in the living cell and the mechanism for regulation and integration of the metabolism; the understanding of the mechanisms and signal transduction pathways for cellular communication
