Educational objectives | Provide students with comprehensive knowledge of the main classes of plant metabolites, including their chemical structures and the biosynthetic reactions that lead to their formation, with a particular emphasis on reaction mechanisms and stereochemistry. Additionally, equip students with a general understanding of crude drugs and bioactive compounds, as well as the most common techniques for extracting and analyzing secondary metabolites. |
Prerequisites | To understand and apply the contents of this course, students must possess knowledge of Organic Chemistry, including functional groups and main reaction mechanisms. Additionally, students should be familiar with the basic concepts of major classes of biologically relevant organic compounds, such as amino acids, sugars, and fatty acids. |
Teaching methods | Frontal lessons with the help of slides on all topics. |
Learning verification modality | Oral examination (10 min) to evaluate the knowledge of the general part (secondary metabolites. Crude drugs and bioactive metabolites. Extraction of crude drugs. Essential oils: preparation, composition and analysis. Biosynthetic pathway of secondary metabolism. (20 minutes). aimed at evaluate the knowledge of the some different biosynthetic pathways of secondary metabolites discussed during the lessons. The oral exam will also enable to evaluate the student's communication skill and capacity in organizing the talk.
