Obiettivi formativi
Within the course on wood chemistry, students first learn the basics of inorganic and organic chemistry. They understand the structure of atoms, the structure of matter, and the chemical reactions that take place in biological and non-biological systems. The focus is on understanding chemical bonds, molecular structure, and the differences between inorganic and organic compounds. A solid basic knowledge of the various elements of the periodic table and their significance in the chemistry of wood and plant cells is imparted. Furthermore, students acquire knowledge about the structure of the plant cell, especially about the chemical processes taking place in the cell organelles. They learn the relationship between basic chemical building blocks such as carbohydrates, lipids, amino acids, and the specific components of the cell wall. This knowledge helps them understand the complex biochemical processes in the plant cell, including the formation and function of the cell wall. A special focus is on the chemical components of wood. Students deepen their knowledge about the main components of the wood structure: cellulose, hemicellulose, lignin, and extractives. Each of these compounds is treated in detail, including their chemical structure. Through this holistic approach, students understand the chemical relationships between the molecular building blocks of the plant cell and the physical and mechanical properties of wood. This enables them to analyze and assess the chemical reactions and transformations that take place during wood processing and utilization. Within the course on wood chemistry, students acquire sound knowledge of inorganic and organic chemistry, including atomic structure, chemical bonds and reactions. They understand the structure of the plant cell and its basic chemical building blocks such as carbohydrates, lipids and proteins, as well as their function in the cell wall. Furthermore, they learn about the most important chemical components of wood - cellulose, hemicellulose, lignin and extractives - in detail. They understand how these components influence the properties of wood and are able to analyze chemical processes during wood processing and assess their impact on material properties. Through this comprehensive approach, students gain a deep understanding of the chemical relationships between the molecular building blocks of the plant cell and the physical and mechanical properties of wood. This enables them to analyze and assess the chemical reactions and transformations that take place during wood processing and utilization.
