OVERVIEW

The course takes into consideration the general principles of Biological Chemistry with particular reference to aspects related to cellular metabolism

AIMS AND CONTENT

LEARNING OUTCOMES

Provide students with a broad general understanding of the principles of biochemistry and molecular biology. At the same time the course offers examples of biochemical and technological applications in various fields.

AIMS AND LEARNING OUTCOMES

Acquisition of basic knowledge on the structure and function of proteins with particular attention to those with enzymatic activity. Use of this knowledge for learning, at the molecular level, of the biochemistry of the main catabolic and anabolic processes. Participation in the training activity (lectures) will allow the student to acquire the knowledge necessary to understand the mechanisms related to cellular metabolism.The student must also acquire a correct terminology, on the main aspects of biological chemistry, in line with the methods of verification of learning.

PREREQUISITES

In order to effectively address the contents of the course, the following basic knowledge is required: 1) general structures of biomolecules 2) general principles of organic chemistry

TEACHING METHODS

 

The lessons take place in the first semester through lectures that make use of slide projections.

EXAMS

EXAM DESCRIPTION

The exam consists of an oral test and is conducted by the professor in charge of the course.The oral examination consists of the answer to questions asked by the teacher on topics covered during the course.

ASSESSMENT METHODS

Assessment of knowledge of: protein structure, enzymology, proteins that bind and transport oxygen, glucose, lipid and protein metabolism, structural formulas of the molecules involved in catabolic and anabolic processes.

This assessment will be verified by means of questions aimed at assessing whether the student has understood the topics of the course. Details on how to prepare for the exam and the degree of detail required for each topic will be provided at the beginning of the course and reiterated during lectures .The student must be able to integrate the knowledge acquired during the lectures The oral examination will focus mainly on the topics covered during the lectures and will have the purpose of assessing the achievement of the appropriate level of knowledge, the ability to use the theoretical notions. The ability to expose the arguments clearly and with correct terminology will also be evaluated.
