Learning objectives
The course aims to enable the student to know and understand the macromolecules of biological interest. The student must understand and be able to describe:1) the structure of the molecules,2) how biological molecules interact and react,3) the functions performed by the molecules that make up the cell, seen as an elementary unit of living matter,3) fundamental aspects of cellular metabolism by locating the reactions’site within the cell.At the end of the course, the student have to demonstrate knowledge and understanding about the biological strategies and interdependence goals between the various phases of metabolism (anabolism, intermediate metabolism and catabolism). The student must acquire an overview of the cellular metabolic processes and their connection with energy consumption and production.The student must be able to apply the knowledge and comprehension skills acquired in carrying out its training activities.
Prerequisites
Basic knowledge of Biology, General Chemistry and Organic Chemistry
Course unit content
General biochemistry: The chemical and structural properties of the main macromolecules present in a cell.Metabolism: the main metabolic processes responsible for producing the energy necessary to keep the cell alive. Metabolic integration.

Teaching methods
Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations, audio-video aids or video-recording of the lectures.
Assessment methods and criteria
The assessment of the achievement of the objectives of the course consists of an oral examination on the whole program of the Biochemistry course.
In the case of coronavirus emergency, the exams will be performed with test online using Teams platforms.
