Plant polysaccharides I: Cellulose
Structure, morphology, stability, dissociated cellulosic materials, commercially important cellulose derivatives, their production, change in properties, main applications, the concept of hydrogels
Plant polysaccharides II: Starch
Structure and chemistry of starch, amylose, and amylopectin, structural features of starch granules, origin–structure relationships, usage of starch, commercially important starch derivatives, their production, change in properties, main applications, a digression on glycogen
Plant polysaccharides III: Annual plant hemicelluloses
Occurrence and structure, role in plant tissue and applications, analytics
Plant polysaccharides IV: Pectins, gums, and beta-glucans
Occurrence and structure, different applications
Plant polysaccharides V: Algae and alginates
Algae as renewable raw material and alginates as fascinating material for different applications, the concept of gel formation based on cation binding
Polysaccharides VI: Chitin and chitosan
Crustaceans as source material of chitin, chitosan as an interesting material for various applications, the concept of gel formation based on different charges
Occurrence, structure as well as possible applications of lignin, collagen, etc.
Plastics: PLA, PHA, et al.
PLA (polylactic acid) as an important example of bioplastics, production, and applications, different ways of modification
Polysaccharides in food and packaging technology
Design for degradation - how biodegradable materials can help for reducing the amount of waste; biodegradability, compostability
Sustainability - some thoughts about a sustainable lifestyle and everyday examples (e.g. textiles).
- Previous knowledge expected
General concepts of chemistry have already been acquired.
- Objective (expected results of study and acquired competences)
The students can name the crucial properties of biopolymers. They can derive general principles from an example that is presented during the lecture. They know about the relation between the molecular structure and properties of the biopolymer. The students know the possibilities and limitations of the industrial application of biopolymers.
