0

Polymerization reaction

Creates large molecules of repeating structure units

1

Condensation reaction (dehydration synthesis)

- monomers are covalently linker by removal of water
- requires energy and catalysts or enzymes

2

Hydrolysis

Breaks covalent bonds between monomers by adding water

3

Carbohydrates

Simple sugars and their polymers

4

Monosaccharides

1) simple sugar where C, H and O are in ratio of 1:2:1
2) major energy for cells, store energy in bonds
3) monomers for complex sugars
4) glucose is most common
5) may form ring in aqueous solutions

5

Disaccharides

Double sugar of 2 monosaccharides

6

Glycosidic linkage

Condensation Rx of 2 monomers

7

Maltose

Glucose+Glucose
Brewing beer

8

Lactose

Glucose+Galactose
In milk

9

Sucrose

Glucose+Fructose
Table sugar

10

Polysaccharides

Macromolecules of up to 1000's of monomers

11

Starch

- Glucose stored in plants of plastids
- Potatoes and grains

12

Glycogen

- Glucose polymer stored in animals
- Stored in muscle and liver

13

Cellulose

- Structural component of plant cell walls
- Humans can't digest

14

Chitin

- polymer of an amino sugar
- exoskeletons of arthropods
