Course-outline of Medical Biochemistry 1

Spring semester of 2017/2018 academical year

  • Name of the course: Medical Biochemistry 1
  • Credits: 3
  • Neptun code: ÁOKOBI463_1A
  • Lectures:Seminars:1.5
  • Director of the course: Prof. Tretter, László MD, PhD, DSc
  • Course-coordinator: Léránt, István PhD +36-20-6632267
  • Student affairs office: EOK-Building, Room 1.508

The aim of the curriculum is to learn and understand the structure-funcion aspects of biologically important macromolecules (proteins, nucleic acids, lipids and complex carbohydrates) and that of their their building blocks (amino acids, nucleotides, sugars and lipids). The enzymology modul deals with the mechanism and efficiency of the in vivo biochemical reactions focusing on their organization into metabolic pathways, their regulation and effectivity. The bioenergetics modul focuses on the energy and metabolite fluxes of the human body and also settle the basis of the thermodinamycal approach of intermedier metabolism.

Seminar reports

Seminar reports

During seminar time through weeks 3-12, – 10 times in total – students will have to report on the lecture and practical topics of the previous week. Missed reports cannot be made up for, students having failed to meet the requirements by week 12 may sit for a written or oral exam during weeks 13-14.

Acknowledgement of the semester

Acknowledgement of the semester

  • Three or less absences in spring semester
  • The total score of the weekly reports has to reach at least 55% of the maximum total score, and no more than two of the evaluated reports (see conditions for evaluation below) may have a score lower than 40%. Acknowledgement (and evaluation) of the semester can be obtained by successful completion of the weekly reports. Alternatively, an opportunity for a written exam on the material of weeks 1-12 will be given during week 13. In case of failure at the written exam students will be given a final opportunity to obtain a “pass” score at an oral exam during week 14.

Grading

Weekly reports during seminars will be held continuously, either in written or in oral form, as announced by the instructor. Evaluation of semester performance will be based on these reports. Failed or missed reports cannot be made up for. For those who participate at all seminars the three weakest reports will be excluded from the evaluation. For those who miss one seminar the two weakest reports, whereas for those who miss two seminars the weakest report, will be excluded. A three-scaled evaluation of semester performance will be based on these reports:

≥ – 75 % excellent (750 points from the possible 1000)

74-55 % satisfactory

54-0 % unsatisfactory

Failed students have to repeat the semester.

Students having failed to meet the semester requirements based on the weekly reports by week 12 will be given the opportunity to pass a written exam on the material of weeks 1-12 during week 13, or, in case of failure of the written exam, an oral exam during week 14. Failure to appear at the written or oral exam must be justified within three business days by submission of appropriate documents.
