The student goal is to develop skills to understand the chemical processes underlying cellular metabolism and the vital functions of living organisms. At the end of the course, the student must be able to identify the functional groups present in natural molecules and to know their physico chemical- characteristics and the reactivity at the base of their transformations.
To this end, the course aims to provide:
- information on the structure, nomenclature and physico-chemical properties of the main organic functional groups;
- skills to recognize the stereochemistry of molecules knowing how to correlate it with the spatial structure of asymmetric carbons;
- knowledge of the structure / activity relationships and of the main organic chemistry reactions with particular regard to the mechanism of functional groups formation and
transformation and to the stereochemistry of products deriving from reactions on chiral substrates.

Stereochemistry: isomers and stereoisomers. Inductive and Resonance effects.
The main reaction mechanisms: electrophilic addition to alkenes, dienes and alkynes. Polymerizations. Electrophilic aromatic substitution on benzene and heteroatoms present in biological molecules. Addition to carbonyls and nucleophilic substitution of acyls. Enolates and their condensations. Bi- and polyfunctional molecules: hydroxy acids, enonic systems, ketoacids. Physico-chemical properties of amino acids (structures and isoelectric point). Carbohydrates (classification, hemiacetal structures, glucosides, polysaccharides).
Nucleophilic substitution (SN1, SN2) and elimination (E1 and E 2) at sp3 carbon. Acetacetic and malonic synthesis. Redox reactions on organic compounds. Radical reactions of hydrocarbons (combustion and radical oxidation) using model reaction (halogenation).
Laboratory experiences (2 CFU): Introduction to organic laboratory precedures. Purification tecnique: crystallization, extraction, distillation and chromatography (adsorption, partitioning, ion exchange, affinity); short references on TLC and gas chromatography. Practical experiences in the laboratory: polarimetry, maleic acid/fumaric acid isomerization, separations by extraction, TLC and column chromatography, esterification.

Type of delivery of the course
The course is based on lectures using pwp presentations and some videos. Exercises and tests will be supplied and solved in class to ease the comprehension.Attendance
Continuous and active attendance is compulsory as the attendance of lab experiencesType of evaluation
Learning verification takes place through a written test and a subsequent oral exam. During the course, in itinere tests will be supplied to allow direct access to the oral examination. All written tests contain 4 exercises, aimed at verifying the level of comprehension of the reaction mechanisms and of chemical compounds reactivity and the students' ability to evaluate their application on a given substrate in the presence of specific reaction conditions. Exam tests (and in itinere tests) from previous years are available on the course website.
