BIOINORGANIC CHEMISTRY

Academic Year 2025/2026 - Teacher: GRAZIELLA VECCHIO

Expected Learning Outcomes

Knowledge and Understanding:

Knowledge of the basic aspects of the chemistry of the elements of the periodic table in biological systems. Understanding the role of biometals and the applications of this knowledge in the biomedical field.

Applying Knowledge and Understanding:

Ability to apply acquired knowledge of inorganic systems to articulate and support arguments related to the topics covered in the course and their practical applications, with particular reference to biological systems.

Solve chemical problems of varying complexity, as well as develop scientific projects.

Making judgements:

Ability to rationalize the behavior of bioinorganic systems based on acquired knowledge.

Ability to find and discuss literature sources in order to develop critical thinking about current ethical and scientific issues.

Communication Skills:

Acquire appropriate language skills in describing aspects of bioinorganic chemistry and chemistry in general.

Interact with other research groups, with interdisciplinary skills relevant to bioinorganic chemistry.

Learning Skills:

Develop the necessary skills for further studies, in-depth analysis, and updates of the acquired knowledge in the field of inorganic chemistry of biological systems, closely related to topics of interest such as environment and health.

Course Structure

The course consists of 6 ECTS credits of theoretical lectures.

Frontal lectures supported by the use of websites that allow dynamic visualization of metalloproteins.

Required Prerequisites

Organic chemistry, inorganic chemistry and biochemistry of the three-year courses.

Learning Assessment

Learning Assessment Procedures

The final exam consists of an oral test, the evaluation of which will take into account the knowledge of the topics asked, the language properties and the critical ability in formulating the answers.

Grade 30 with honors: The student demonstrates an in-depth knowledge of all the topics covered, showing a fully developed ability to critically correlate various aspects, along with excellent communication skills and language proficiency.

Grade 27–28: The student demonstrates a good knowledge of all the topics covered and presents them clearly using appropriate language.

Grade 25–26: The student has a fair knowledge of all the topics covered, is able to integrate and analyze information with sufficient critical thinking, and expresses themselves more than adequately.

Grade 24–25: The student has a more than sufficient knowledge of all the topics covered, is able to integrate and analyze content with sufficient critical thinking, and expresses themselves more than adequately.

Grade 18–22: The student has a sufficient knowledge of all the topics covered, shows limited ability to critically relate the relevant chemical aspects, and presents topics with acceptable clarity, although language proficiency is poorly developed.

Exam not passed: The student does not demonstrate the minimum required knowledge of the course’s basic content. Their ability to use specific terminology is extremely poor, and they are unable to independently apply the knowledge acquired.

Examples of frequently asked questions and / or exercises

The material useful for the preparation of the student and for passing the exam will be available on studium and will be discussed during the lessons.
