Prerequisites: None
Target skills and knowledge: The course describes in general terms the study of structural properties of biological macromolecules, such as polypeptides and proteins, polynucleotides and polysaccharides. The course is divided into three parts: in the first one, the structural properties of natural and synthetic biopolymers are described and discussed while the second describes some industrial applications of artificial and natural biopolymers and biocompatible and/or biodegradable polymers; finally, the main methods for the study of conformations, interactions and conformational transitions of biopolymers are considered in the third part.
Examination methods: Oral.
Assessment criteria: The acquisition of the knowledge and of the abilities described above will be evaluated.
Course unit contents: The program is divided into the following points:
1) Polypeptides and protein macromolecules.
Chemistry and stereochemistry of peptide residues. Concepts of primary, secondary, tertiary and quaternary structure. Fundamental aspects of sequencing and synthesis of polypeptides. Outline of molecular biology techniques for the production of proteins. Description of various types of ordered conformations of polypeptide chains. Outline of predictive methods of secondary and tertiary structures. Conformational analysis and forces that determine the structure of peptides and proteins.
2) Polynucleotides
Chemistry and stereochemistry of nucleotides. Typical properties of purine and pyrimidine bases and their derivatives. Primary, secondary, tertiary and quaternary structures of nucleic acids. Structural differences between DNA and RNA. Conformational analysis and forces that determine the structure of nucleic acids. PCR.
3) Polysaccharides
Chemistry and stereochemistry of structural units of polysaccharides. Structures of monosaccharides, disaccharides, homopolysaccharides, heteropolysaccharides. Mention of the structure of some peptidoglycan.
4) Industrial Biopolymers
Biomass. Concept of Biorefineries. Production of energy and chemicals from biomass.
Modified polysaccharides in the food industry.
Modified polysaccharides and plastics: blends of starch and synthetic polymers, acidic polysaccharides, cellulose, chitin, chitosan.
Development and production of polymers from renewable sources. Derivatives of vegetable oils. Polyhydroxyalkanoates. PLA. Protein derivatives.
Biocompatible polymers. Hyaluronic acid and derivatives. Polymeric biomaterials.
5) Analytical techniques for the study of the structural properties of biopolymers.
Characterization and separation of biopolymers on the basis of their hydrodynamic properties: ultracentrifugation, diffusion, electrophoresis, light scattering, size exclusion chromatography.
Spectroscopy applied to the study of biopolymers: absorption spectroscopy, circular dichroism, IR, fluorescence.
Planned learning activities and teaching methods: Classroom lectures.
Additional notes about suggested reading: Handouts and students’ notes.
