Contribution of the course to the overall degree programme goals
Educational objectives of the teaching are: i) to acquire the knowledge and understanding of the main concepts of chemistry and physics applied to biological disciplines; ii) to critically investigate and comprehend the structural and chemical proprieties of the major biological macromolecules; iii) to promote and stimulate the use of a logical and deductive analysis necessary to quantitatively solve simple assignments of chemical biology, either alone or as part of small work units; iv) to develop the ability to expose scientific concepts in a formal manner and using a proper scientific language.
Expected learning outcomes
i) Knowledge of the chemical-physical properties of the biological macromolecules and understand the key relationships between structure and reactivity;
ii) Being able to make logical connections between different course’s subjects.
2. Ability to apply knowledge and understanding
i) Being able to use the acquired knowledge to comprehend and logically interpret the chemical-physical properties of the biological macromolecules;
ii) Being able to apply the acquired knowledge to solve simple assignments using a logical and deductive approach.
3. Ability to judge
i) Being able to apply the acquired knowledge to perform a critical analysis of the structural and chemical proprieties of the biological macromolecules;
ii) Being able to recognize errors through a critical analysis of the applied method and to formulate different hypothesis.
4. Communication skills
i) Being able to convey the acquired knowledge using an appropriate terminology;
ii) Being able to interact with the teacher and the classmates in a respectful and constructive manner, especially during the execution of the assignments carried out in a group.
5. Learning skills
i) Being able to take notes, selecting and collecting information according to their importance;
ii) Being able to solve independently simple assignments of chemical biology.

As a supplementary reading, the following texts are recommended:
- D. Van Vranken, G. Weiss: Introduction to Bioorganic Chemistry and Chemical Biology, Garland Science – Taylor & Francis Group;
- G.T. Hermanson: Bioconjugate Techniques, III ed., Academic Press – Elsevier (freely and legally available in electronic format, in the university network, at the following website: https://www.sciencedirect.com/book/9780123822390/bioconjugate-techniques ).
Specifically, the written test consists of:
- eight open questions concerning all parts of the program reported in the "Contents" section: students must thus demonstrate both the learning of the topics taught in class and the ability to expose them in a formal and concise manner using an appropriate scientific language;
- four exercises related to all the parts of the program reported in the "Contents" section: the students must in this way prove to be able to correctly solve the given problems, reporting the units of measurement and write all the calculation steps in a formal manner. This test aims to verify that the students have acquired the concepts dealt with during the lessons and knows how to apply them with consistency in order to solve scientific problems.
During the written test, only the scientific calculator is allowed. The use of notes, textbooks, phones and other electronic apparatus is not allowed, under penalty of exclusion from the final.
The evaluation is expressed in thirtieths. Finals will take place within the dates established by the academic calendar.
The teaching material is present and downloadable from the University's Moodle e-learning platform.
Accommodation and support services for students with disabilities and students with specific learning impairments: Ca’ Foscari abides by Italian Law (Law 17/1999; Law 170/2010) regarding support services and accommodation available to students with disabilities. This includes students with mobility, visual, hearing and other disabilities (Law 17/1999), and specific learning impairments (Law 170/2010). In the case of disability or impairment that requires accommodations (i.e., alternate testing, readers, note takers or interpreters) please contact the Disability and Accessibility Offices in Student Services: email@example.com
