|The course gives an orientation in the methods that are used for purifying biomolecules. Focus usually is made on proteins, but other biomolecules are also be treated. The course mainly describes methods to prepare cell extracts and preparation of samples, centrifugation, filtering, precipitation, the theoretical and practical bases of chromatography, gel-filtration, ion exchange chromatography, hydrophobic interaction chromatography, reverse-phase chromatography, affinity chromatography, etc. during the purification of biomolecules.
|*Purification Techniques of Biomolecules course is designed mainly to accomplish the following objectives;
*Explain the intermolecular interactions: mechanism of covalent and noncovalent interactions, charge-charge interactions, hydrogen bonds, Van der Waals forces and hydrophobic interactions.
*Describe ionization of water: acid/base chemistry as it applies to biological molecules.
*Comprehend structure and function: basic molecular properties of the 4 classes of biological molecules (proteins, carbohydrates, lipids and nucleic acids) and the subunits from which they are formed. Explain how the structure of biological molecules dictates function and how changes in structure direct biochemical reactions.
*Define organic reaction mechanisms: the network of chemical reactions that make up central metabolism.
*Acquire general background in the field of purification of biomolecules: comprehend scientific literature pertaining to subject matter in purification stratagies.
*Approach to scientific mysteries: apply knowledge & concepts to novel problems.
