BIOCHIMICA GENERALE E DELLA NUTRIZIONE

General Biochemistry and Biochemistry of Nutrition: The course aims to describe the main characteristics of the macromolecules of biological interest and to provide students with the cognitive tools for understanding the biochemical peculiarities of liver, muscle, adipose tissue, kidney, blood and of the existing metabolic interrelations among the main tissues. In addition, the course also provides the basis for understanding the main metabolic dysfunctions based on nutrition.

Frontal teaching, power-point lessons, exercises and cooperative learning.

If the teaching is carried out in mixed or remote mode, the necessary changes may be introduced in order to respect the program envisaged and reported in the syllabus.

Information for students with disabilities and/or ASD:

To guarantee equal opportunity and in compliance with the laws in force, interested students can request a personal interview in order to plan any compensatory and / or dispensative measures, based on the educational objectives and specific needs.

It is also possible to contact the referring teacher CInAP (Center for Active and Participated Integration - Services for Disabilities and / or DSA) of our Department, Prof.ssa Santina Chiechio.

Students must have passed the General Chemistry exam (preparatory). Finally, students are required to have adequate knowledge of biology, in particular on the structure of the cell and of the various cell compartments.

The exam will be written with multiple choice. Verification of learning can also be carried out electronically, should the conditions require it. The test focuses exclusively on the topics covered in class. The type of exercises of the exam will be addressed during the course. The exam dates are published on the website of the Department of Pharmaceutical and Health Sciences.
