Carbohydrates Flashcards
1
Q
What types of glycosidic bond do amylose, amylopectin, glycogen and cellulose have?
A
1) amylose:1-4
2) amylopectin: 1-4, 1-6
3) glycogen: 1-4, 1-6
4) cellulose 1-4
2
Q
If something is branched what does it mean?
A
Rapid hydrolysis because lots of points for the enzyme to access
3
Q
Amylopectin shape?
A
Elliptical
4
Q
Glycogen:
- hydrolysis?
- shape?
- type of glycosidic bond?
- osmotic affect?
A
- rapid hydrolysis because it’s branched
- spherical
- alpha glucose 1-4 and 1-6
- no effect
5
Q
Amylose:
- hydrolysis?
- shape?
- type of glycosidic bond?
- osmotic affect?
A
- Slow hydrolysis for respiration because there are only 2 enzyme attachment points (doesn’t matter anyway because plants respire slowly)
- coiled
- alpha glucose 1-4
- fewer OH groups (bc compact) exposed on helix so less of an osmotic affect

Q
Amylopectin:
- hydrolysis?
- shape?
- type of glycosidic bond?
- osmotic affect?
A
