AIMS AND CONTENT

LEARNING OUTCOMES

We aim at giving fundamental knowledge on the structure and metabolism (anabolism and catabolism) of biomolecules, with a special focus on metabolism, integration and functional integration of human organs.

AIMS AND LEARNING OUTCOMES

Students will learn to recognize, write and describe the structure of the main biomolecules (lipids, proteins, carbohydrates, nucleotides). In addition, they will be able to distinguish the main anabolic and catabolic pathways, connecting them in the different metabolic conditions. They should be able to understand and discuss the role of enzymatic regulation (also with knowledge of Kinetics and thermodynamic) in the different metabolic pathways.  Students should be able to correlate the signaling pathways activating different metabolic response in different organs, with a focus on the (dys)functional integration between different human organs.

TEACHING METHODS

Frontal Teaching. Seminars. Examples of the use of elementary biomedical databases to search information.

SYLLABUS/CONTENT

 

  • Structure, properties and functions of aminoacids and proteins.

  • Principles of bioenergetics and biosignalling.
  • Role of ATP and other phosphorous compounds. General principles of metabolism, catabolism, anabolism.
  • Carbohydrate metabolism: Glycolysis, gluconeogenesis and regulation. Ketone bodies. Glycogen synthesis, glycogen lysis and their reciprocal regulation in muscle and liver. Pentose phosphate pathway: oxidative and non-oxidative phase, metabolic meaning and regulation. Glutathione. Clinical tests for glucose metabolism.

LESSONS

TEACHING METHODS

Frontal Teaching. Seminars. Examples of the use of elementary biomedical databases to search information.

LESSONS START

Lessons will start in the second semester, according to the timetable.

Class schedule

All class schedules are posted on the EasyAcademy portal.

EXAMS

EXAM DESCRIPTION

Oral examination, approximately 15-20 minutes.

ASSESSMENT METHODS

The level of aim achievements will be verified with a discussion by the student, that will start from a given subject on a specific metabolic pathway, from which connections to other metabolic pathways, regulation systems and/or correlation among different organs will be developed.
