OVERVIEW

The course of Biomedical Chemistry aims to provide the student with the basic biochemical knowledge for the acquisition of fundamental theoretical and practical skills to follow the other biological courses within the Degree in Chemistry

 

AIMS AND CONTENT

LEARNING OUTCOMES

At the end of the course, the student should knows: - biological processes at the molecular level; - biomolecular structure-function relationships; - energy metabolism; - the main metabolic processes; - the basics of biochemistry and enzymology.

 

 

AIMS AND LEARNING OUTCOMES

Acquisition of basic knowledge on the structure and function of proteins with particular attention to those with enzymatic activity, to use this  knowledge for the molecular, biochemical understanding of the main catabolic and anabolic processes.
