General description A asignatura Bioquímica Estructural resulta imprescindible, dende un punto de vista básico, para entender as principais propiedades químicas, biofísicas e estruturais das macromoléculas biolóxicas, e a relación que existe entre estas propiedades e as diversas funcións que desempeñan. Os coñecementos adquiridos resultarán imprescindibles para outras asignaturas do Grao en Nanociencia en Nanotecnoloxía.

Methodologies
Methodologies Description
Guest lecture / keynote speech The subjects of the subject will be taught by the professors and all the presentations or other documentation will be made available to the students on the Virtual Campus.
Laboratory practice A series of activities will be carried out in the practice laboratory, so that students learn to handle scientific instruments and basic procedures in Biochemistry and Molecular Biology. A brief memory will be delivered at the end of them.
ICT practicals A series of activities will be carried out in the computer room, so that students learn to handle different databases and computer tools in the field of protein structural biology. A practical group work will be proposed once the necessary knowledge has been acquired.
Mixed objective/subjective test Written test used to evaluate learning, and that can combine different types of questions: multiple choice, association, explanatory or calculation questions and problem solving.

Assessment comments
-LABORATORY PRACTICES are compulsory. Students who do not complete ALL the practices without a duly justified reason prevent them from passing the subject. OFFICIAL CHANCE FOR JUNE A.-To pass the subject it will be necessary to reach 45% of the points, in each of the Evaluable Parts: Objective Test, Laboratory Practices and ICT Practices. B.-HONOURS ENROLLMENT: Those students who take the first opportunity (official exam in June) will have priority to apply for MH. JULY OFFICIAL OPPORTUNITY A.-To pass the subject it will be necessary to reach 45% of the points, in each one of the Evaluable Parts: Objective Test, Problem Solving and Laboratory Practices. Final Qualification, in the Minutes: In any of the 2 Options: June or July, ONLY the qualifications of all the Parties (Objective Test, Laboratory Practices and ICT Practices) will be added if they all reach 45% of their value. If this percentage is not reached in any of them, only the note of 4 will appear in the Minutes. CONSIDERATION OF NOT PRESENTED (NP): 1st Opportunity in June: The student who does not appear for the objective test on the official date. 2nd Opportunity of July: A NOT PRESENTED will apply when the student does not appear for any of the evaluable parts. Exceptional cases: Exceptionally, in the event that the student, for duly justified reasons, has not been able to take all the continuous assessment tests, the teacher(s) will take the measures that he/she deems appropriate for this purpose. .-For students with partial dedication or exemption from attendance, a specific global assessment exam will be held in the June and July sessions.
