16. Sugars Flashcards
1
Q
Give examples of monosaccharides
A
glucose, fructose and galactose
2
Q
Give examples of polysaccharides
A
starch, glycogen and cellulose
3
Q
Structure of starch
A
It has different forms of polysaccharides amylose a straight chain polymer with α-1.6 linkage and amylopectin branched structure with α-1.6 and α-1.4 linkages
4
Q
Structure of cellulose
A
Consists of straight chain polymer that has a β-1.4 linkage. The β-1.4 can be hydrolyzed by the enzyme cellulase, which is absent in most animals
5
Q
Glucose (structure, functional group etc.)
A
- Monosaccharide
- Functional group: ketone
- source of energy
- added in food and drinks to make them taste better
6
Q
Fructose (structure, functional group etc.)
A
- Monosaccharide
- Functional group: aldehyde
- source of energy
- fuels cellular respiration
7
Q
Hydrolysis of polysaccharides
A
When polysaccharides undergo hydrolysis, breaks the polypeptide bonds and 2 monosaccharide forms
