Intended learning outcomes
Glycobiology and Carbohydrate Technology will provide the student with an overview of carbohydrates (sugars) as an important class of biomolecules involved in numerous biological functions and industrial applications. Knowledge of carbohydrate and glycoconjugate functions, structures, modifications and biosynthesis will prepare the students for problem solving in the areas of food, feed, health, energy and materials. Especially possibilities and challenges related to sustainable development using renewable carbohydrate raw materials will be emphasized. The course is designed to build upon and compliment the student’s knowledge of molecular biology/biotechnology, protein structure & function, and molecular enzymology obtained from other courses in the Biotechnology programs.
Carbohydrate structure-function relationships will be highlighted using numerous examples from plant, animal, and microbial systems. Particular attention will be paid to the enzymes responsible for carbohydrate biosynthesis, modification and biodegradation: carbohydrate-active enzymes (CAZymes). The interactions of carbohydrates with various non-catalytic proteins (lectins and carbohydrate-binding modules) will also be covered. Through specific examples and case studies, special focus will be placed on carbohydrate-protein/enzyme interactions in the context of important applications, including: glycoprotein pharmaceutical development, biofuel production, modification of wood and textile fibers, food production and human nutrition, brewing, treatment of inherited metabolic disorders, and treatment/prevention of pathogen infection, including influenza. The acquired complete knowledge base will aid students in their future studies and/or in an industrial employments to forsee future challenges and developments in the scientific area
Upon completion of the course, the student will be able to:
- describe carbohydrate structure on the mono-, oligo-, and polysaccharide organizational levels and discuss the interaction of carbohydrates with other biopolymers as structural components in various cell types
- describe the importance of the pool of sugar phosphates as precursors in carbohydrate biosynthesis
- describe the molecular mechanisms of key enzymes involved in the biosynthesis and biodegradation of carbohydrates across diverse kingdoms
- discuss the structural diversity of carbohydrate-active enzymes and carbohydrate binding proteins in terms of their biological functions, and outline how these biocatalysts can be used in enzyme technology to develop environmentally-friendly sustainable processes in vitro or increase plant biomass in planta
- describe and use the CAZy database, and identify candidate genes encoding enzymes potentially relevant for bioconversion
- describe the biosyntheses of glycoproteins and glycolipids and discuss their diverse biological functions including disease states
- understand and discuss the importance of carbohydrates as raw material for sustainable development and describe molecular details of selected examples of “carbohydrate biotechnology” in biorefinery (biofuels and biofiber), food, and medical applications
- understand and critically evaluate contemporary research literature dealing with various aspects of carbohydrate structure, biochemistry, enzymology, and applications thereof
- explain and discuss influenza pandemics and understand the risk and threat of a new pandemic as well as discuss ethical and social aspects of bioethanol production, enzymatic HFCS conversion, production of gum arabic, use of phytases, GMOs, and lab-modified influenza viruses
Course main content
Lectures will form the basis of the course. Attendance of all the lectures is strongly encouraged. Lecture periods will serve as the primary mode of instructor-student interaction, including passing various practical information to the students. A certain amount of time scheduled for lectures will be used for questions/answer sessions, small assignments, discussions and to go over practical assignments. Moreover, short videos will be integrated in order to enhance learning, visualize and explain difficult biological concepts and inspire debate.
Assignments & computer graphics laboratory:
Throughout the course, exercises will be assigned which are designed to improve learning of various topics in the course. These assignments will form the basis for in-class discussion, and successful completion of these assignments will greatly improve chances for success on the final examination. Similarly, a computer graphics laboratory exercise will provide important understanding of structure-function relationships in carbohydrate-active enzymes. Completed and passed assignments may give the students the opportunity to get bonus points for the final examination.

Requirements for final grade
To pass the course students should actively participate in course meeting activites and discussions.
The student’s final grade in the course will be based on performance on a final written examination. This examination will consist exclusively of essay-style questions which will test the student’s overall comprehension of the various topics covered in the course.
