- the basic knowledge of structure and function of the biological macromolecules.
Course contents summary
General and Inorganic Chemistry
Elements and compounds. Sub-atomic particles. Atomic number, mass number, isotopes. Atomic structure. Electronic configuration of the elements.
Periodic table. Periodic trends in the chemical properties of the elements.
Chemical bonding: ionic bond; covalent bond (pure, polar, dative). Intermolecular bonding.
Atomic and molecular weight, gram atom, gram molecule; related exercises and stoichiometric calculations.
Inorganic chemical compounds: hydrurs, binary acids, oxides, anhydrides, peroxides, hydroxides, acids, neutral and acidic salts; formation reactions, reaction balancing, nomenclature.
