Syllabus

Common characteristics of the Integrated Course unit

Prerequisites: Basic knowledge of inorganic and organic chemistry
Target skills and knowledge: The student will be familiar with cellular and whole-organism metabolism and will acquire the information necessary to understand cellular biology and physiology classes.
Examination methods: Written examination with both multiple choice and open questions
Assessment criteria: The student has to provide evidence of having understood and studied the information given during the lectures and those found in the textbooks.

Specific characteristics of the Module

Course unit contents: Proteins. Amino acids: structure, properties and classification. Modified amino acids. Structures and properties of the peptide bond. Polypeptides chains. Peptides of biological interest. Levels of structure in protein architecture. Primary structure. Ramachandran plot. Tridimensional structure of the proteins. Secondary structure: alpha-helix, beta-sheet, beta turn. Fibrous proteins (fibroin, keratin, collagen, elastin). Super secondary structures. Tertiary structure. Globular proteins. Structural domains and structure/function relationship. Denaturation. Molecular dynamics of globular proteins. Secondary structure prediction and relationship between primary sequence and tridimensional structure. Protein folding. Quaternary structure.

Oxygen-transporting proteins. Myoglobin and hemoglobin. Oxygen binding. Cooperative binding. Allosteric effects and allosteric factors. Bohr effects. Fetal hemoglobin and hemoglobin S.

Enzymes. Catalysis and enzyme kinetic. Michaelis–Menten model. Significance of vmax, Km and Kcat and their calculation. Energetic profile of an enzymatic reaction. pH effect in enzymatic catalysis. Regulation of enzymatic activity: inhibition, allosteric regulation, covalent modifications, proteolytic cleavage. Role of coenzymes and metal ions. Catalytic mechanisms: serine proteases.

Carbohydrates. Monosaccharides, disaccharides and their products. Oligosaccharides. Polysaccharides. Omo- and hetero-polysaccharides. Glycoproteins and glycolipids. Structure and function.

Nucleotides and Nucleic acids. Nucleotides and phosphodiester bond. The nature of nucleic acids: RNA, DNA and their primary structure. Secondary structures of DNA: helix A;B and Z. Denaturation of DNA molecules. RNA and its tridimensional structures. ATP, FMN, FAD, NAD+.

Lipids and Biological membranes. Structure and properties of lipids (fatty acids, triglycerides, waxes). Membrane lipids (glycerophospholipids, sphingolipids, glycolipids and cholesterol). Lipophilic vitamins. Structure and properties of the cellular membranes. Fluidity and asymmetry of the membranes. Membrane proteins and their structure. Transport across membranes: mechanisms and classification.

Cell Signalling. Examples of molecular mechanisms of signal transduction.

Practicals: Spectrophotometry theory and application. Absorbance spectrum of Flavin mononucleotide (FMN) in oxidized and reduced form. Determination of protein concentration by biuret method. Lactate dehydrogenase activity: experimental determination of vmax and Km values.
Planned learning activities and teaching methods: 48 hours lectures and 16 hours practicals
