Monomers -> Polymers - Polysaccharides Flashcards
1
Q
Polysacharides
What are polysacharides
A
Long chains polymers of sugars and sugar derivatives
*Primarly used for storage of energy and cell structure
2
Q
Polysacharides
What are the monomers of polysacharides
A
Repeating units of polysacharides are monosacharides
3
Q
Polysacharide
What types of sugars are present
A
- Aldehydes, Aldosugars (terminal carbonyl end), Ketosugars
- Ketosugars = internal carbonyal group
4
Q
Monosacharides
Glucose
A
- Most common monosacharide is aldohexose D-Glucose C6H12O6
- D-Glucose has two fourms Alpha (hydroxyl group is down - plants), Beta (hydroxyl group is up - humans)
5

- Starch - in plant cells
- Glycogen - in animal cells and bacteria
11
Q
Polysacharides
What are the structural polysaccharides
A
- Cellulose - plants (B-D-glucose)
- Chitin - insects and crustacians
