Polysaccharides - Prior knowledge - Polysaccharides: Functional properties
6 important questions on Polysaccharides - Prior knowledge - Polysaccharides: Functional properties
What are factors that influence the viscosity?
- Conformation of monosaccharide unit - alpha/beta
- Branching pattern - e.g. Many/few branches
- Degree of polymerisation (DP) - # of monomeric units
- Presence of charged groups - e.g. Uronic acid
How does the conformation of the monosaccharide unit influence viscosity?
How does the branching pattern influence the viscosity?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How does the degree of polymerisation (DP) influence the viscosity?
How does the presence of charged groups influence the viscosity?
What are the functional properties of polysaccharides?
- Can give viscosity: movement causes friction
- Can make a gel: network that retains water
- Effect depends on structural/chemical characteristics
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
