Course unit structured in the following modules:

Learning objectives

The student will have to become familiar with the name and the corresponding chemical formula of the substances of biochemical-clinical interest. It will also have to know how to recognize the functional groups of the molecules. The student will have to acquire an overview of the cellular metabolic processes, their connection with consumption and the production of energy and how this is based on the concept of living being.

Course unit content

The course aims to provide essential information on the structure of biological macromolecules and their chemical properties. The student will have to learn how the molecules react and acquire knowledge on the functional role of the biomolecules that make up the cell, seen as an elementary unit of living matter. The student must also understand the fundamental principles of cellular metabolism.

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 exam includes a written test that will focus on the entire program of the course. To pass the exam you must respond appropriately to a number of questions covering the whole program.
In the case of coronavirus emergency, the exams will be performed with written test online using Teams and/or Elly platforms.
