Contents
The General and Molecular Biochemistry course introduces the student to the structure and functions of molecules of biological interest, their metabolism and their metabolic interactions and their role in various organs and tissues.
Reference texts
I principi di Biochimica di Lehninger – David L et al., Zanichelli
Educational objectives
The main objective of the teaching is to provide students with the basics for achieving a good level of knowledge of the structure and metabolism of biological molecules.
The main knowledge acquired will be:
- structure of carbohydrates, lipids, proteins and nucleic acids;
- structure, function and mechanisms of regulation of enzymes;
- identification of the role of vitamins and minerals in metabolic processes; - catabolic and anabolic pathways of the different macromolecules;
- role of hormones in different metabolisms;
- metabolic interactions between different organs and tissues
Prerequisites
In order to understand and know how to apply the topics covered in the course it is indispensable to have passed the exam of biology and organic chemistry
Teaching methods
Frontal lectures with projection of images and video
Other information
Frequency is recommended. he teaching material presented in class will be included on the UNISTUDIUM platform so that working students can also view it and use it for study.
Learning verification modality
A final oral test will be carried out which will evaluate the knowledge acquired and the ability to connect between the different topics
