Learning outcomes
The student has a knowledge of the most important biomolecules, as carbohydrates, lipids, aromatic polyketides, terpenes, peptides and proteins, alkaloids, antraquinones, flavonoids and terpenes. A particular attention will be devoted to the study of structure, biosynthesis and purification methods of natural compounds that are used in cosmetic formulations and are obtained from plants. The student will also learn the chemical properties of the molecules used in the preparation of aromas and fragrances.

The topics listed in the program will be fully covered.
In the lab activity, students will do experiments above listed. Lab work will be based on collaborative work by small groups two or three students, under the supervision of the teacher.
The lab activity is compulsory.
As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class or on Microsoft Teams according to the modality chosen by the teacher. Information about Module 3 attendance schedule is available on the website of your degree programme.
Assessment methods
The preparation is tested by an oral exam, on the subjects described during the course.
