Learning objectives
The aim of the course is to provide students with all the knowledge needed to master the basics of biological chemistry, particularly with regard to the understanding and study of the major biological processes in living organisms.
Expected learning outcomes
Students will acquire the ability to relate the fundamental features of living systems and of the transformations that occur in them to the underlying chemical and physical principles governing the involved chemical species; to handle quantitatively protein-ligand interactions and enzyme kinetics; to interpret biological phenomena based on the principles of thermodynamics. They will be familiar with the biologically relevant organic compounds such as carbohydrates, aminoacids and peptides.
Course syllabus and organization

Single session

Responsible
More specific information on the delivery modes of training activities for academic year 2021/22 will be provided over the coming months, based on the evolution of the public health situation.
Course syllabus
Structure, chemical properties and reactivity of carbohydrates (mono-, di- and polysaccharides).
Nucleic acids: bases, nucleosides, nucleotides, base-pairing, DNA structure. Lipids.
Structure, chemical properties and reactivity of amino acids. Chemical synthesis of peptides (in solution and in solid phase, protective groups). Primary structure of peptides (chemical and enzymatic hydrolysis).
Protein structure and folding.
Enzymes: basis concepts and kinetics, cofactors and coenzymes, the Michaelis-Menten equation, regulation of the enzymatic activity.
Enzymatic inhibition: reversible (competitive, incompetitive and non-competitive) and irreversible inhibitors.
Serine proteases: general properties, three dimensional structure, activation and catalytic mechanism.
Bio-energetics: high-energy compounds. ATP and other phosphorylated compounds. Redox reactions. Electron carriers: NAD+ and FAD.
Metabolism: basic concepts and regulation, glycolysis, diverse fates of pyruvate, citric acid cycle, electron transport and oxidative phosphorylation.
Prerequisites for admission
Basic knowledge of General and Inorganic Chemistry, and of Organic Chemistry.
Teaching methods
Teaching Mode: Classroom lectures, including theory, exercises, and application examples, with Powerpoint presentations. At the end of the course, there will also be seminars held by experts in the field of applied biological chemistry.

Copies of the slides projected in the classroom as well as other materials will be made available through the course website on the ARIEL platform of the University of Milano (https://mnardinicb.ariel.ctu.unimi.it/v5/home/Default.aspx). By no means, this material replaces the lectures or a textbook. The material is made available only to registered students of the Degree Course in Molecular Biotechnology and Bioinformatics and should not be distributed to others.
Assessment methods and Criteria
The exam consists of a written test that aims to ascertain the student's knowledge of the theoretical and practical aspects of the subject covered in the course. The written test requires the answer to open questions and/or the solution of application-type exercises, with contents and difficulties similar to those faced during the course. During the exam, the consultation of texts or notes is not allowed. The final evaluation will result from the joint evaluation of the two teachers.
