This course is an introduction to basic biochemistry and chemistry activity in the cell and examines the structure and function of fundamental chemicals of living organisms: carbohydrates, lipids, proteins, enzymes, inorganic ions and water. Topics include: fundamental chemicals of living organisms; monomers and chemicals bonds; carbohydrates; disaccharides and polysaccharides; lipids; the role of lipids in organisms; proteins; dipeptides and polypeptides; quaternary structures; inorganic ions; roles of calcium and iron; pH; colloids; water; enzymes: role, protein nature, mode of action and substrate, properties, denaturation and inhibition. This course is the prerequisite for Bioenergetics.
