Course detail

Introduction to Chemistry of Natural Materials

FCH-BC_UCHPMAcad. year: 2024/2025

The interpretation begins with the main biological medium - water. This is followed by the theme of the most widely used biopolymer - cellulose. The topic of cellulose and its primary localization in plants is related to the theme of porphyrin compounds and their complexes. The functionality of these complexes determines the existence of another significant starch polymer. And the topic of plants is directly related to humic substances. The effect of coevolution of various organisms will be explained by the beta (1-3) -D-glucan example and its effect on the immune response of the human organism. The topic of betaglucans is closely linked to chitin, due to the existence of a chitin-glucan complex in fungi. The principles of functionality of building proteins will be mentioned in the topics of keratin and collagen. All of the above are linked to both environmental and ethical issues that the course participants will look for for their answers.

Aims

The aim of the course is to acquaint students with the basic principles, materials and materials occurring in a natural environment with an emphasis on the chemistry of biopolymers.
Upon completion of the course the student will focus on issues related to important representatives of biopolymers and other natural substances and their role in nature. Emphasis will be placed not only on the understanding of the relationship between primary structure and higher structures, but also on the involvement of chemical individuals in complex matrices occurring in living systems. On selected examples the student will be able to derive general characteristics for a given group of substances. The student will focus on the evolution of biopolymers as well as be aware of the environmental implications of biopolymers. At the same time, a basic orientation in the ethics of biopolymers is assumed.
