High latent heat of evaporation
Very cohesive
Lower density when solid
God solvent

2

What are the functions of water?

Important in reactions
Used to transport substances
Helps with premature control
Water is a habitat

3

What elements are carbohydrates made of?

Hydrogen, carbon and oxygen

4

What is the general formula of carbohydrates?

Cx(H20)Y

5

What is a polymer?

Long chain molecules
Linked up by monomers in a repeating pattern

6

What are the two types of glucose?

Alpha and Beta

7

Draw an alpha glucose molecule

...

8

Draw an beta glucose molecule

...

9

Describe the structure of glucose

A monoscaccride with 6 carbon rings

10

Describe the structure of ribose

A monoscaccride with 5 carbon rings

11

Draw a verbose molecule

...

12

What bond are monosaccharides joined by?

glycosidic bonds
This is a condensation reactions (releases water)

13

What is a monosaccharide?

It is a simple sugar (CH4O)n

14

What is a disaccharide?

Double sugar two monosaccharide

15

What is a polysaccharide?

large molecules from many monosaccarides joined through condensation and glycosidic bonds

16

Describe the structure of the statch amylose

Long unbrached
alpha glucose
Coiled structure
very compact therefore its good for stoage

17

Describe the structure of the statch amylopectin

Long branched
alpha glucose
Its in rows allowing it to be broken down easily and quickly

18

What is a hydrolysis reaction?

It is the breakdown of di/polysaccharides with addition of water molcules

19

What is the structure of glycogen?

Main energy storage in animals
Branched
Alpha glucose
Very compact
Storage molecule

20

What is the structure of cellulose?

Unbranched chains
Component in plant cell walls
Beta glucose
Provides structural support
Straight shains

21

Compare glycogen and cellulose

Glycogen:
- Alpha glucose
- Branched
- Storage molecule

Cellulose:
- Beta glucose
- Unbranched
- Structural molcule

22

What makes up a triglyceride?

One glycerol molecule
Three fatty acid molcules

23

What type of bond is formed between the glycerol and fatty acids

Ester bonds

24

Draw the chemical structure of a tryglceride

...

25

Which part of a fatty acid is hydrophobic and hydrophilic?

Tail hydrophobic
Heads Hydrophilic

26

What is the difference between saturated and unsaturated

Unsaturated has at least one carbon double bond

27

What makes up a phospholipid

One glycerol molecule
Two fatty acid molecules
One Phosphate group

28

What are the main functions of triglycerides?

Energy storage in plants and animals
Insoluble
Heat (insulation)

29

What are the main functions of phospholipids?

Make up a bilayer
Used in cell membranes

30

What are the main functions of cholesterol?

It helps strengthen cell membranes
