What do organic compounds contain?

Carbon

1

What are the exceptions of carbon which aren't in organic compounds?

Hydrogen carbonates (HCO3-), carbonates (CO3^2-) and oxides of carbon (CO,CO2)

2

What are inorganic compounds made of?

All other compounds

3

Carbohydrates- what are they?

Are organic compounds consisting of one or more simple sugars that as monomers follow the general formula (CH2O)

4

Carbohydrates- Draw the example glucose and ribose

Glucose- C6H12O6
Ribose-C5H10O5

5

Carbohydrates- what is monosaccharide?

Any class of sugars (e.g glucose) that cannot be hydrated to give a simpler sugar

6

Carbohydrates- give 3 examples of monosaccharides?

Glucose, galactose, fructose

7

Carbohydrates- what does disaccharide mean?

Any class of sugars whose molecules contain a 2 monosaccharide residues.

8

Carbohydrates- give example of disaccharide

Lactose, maltose, sucrose

9

Carbohydrates- what is polysaccharide?

A carbohydrate whose molecules consist of a number of sugar molecule bonded together

10

Carbohydrates- give examples of polysaccharides

Cellulose, glycogen and starch

11

Carbohydrates- what is the function of glucose in animals?

Source of energy which can be broken down to form ATP via cellular respiration

12

Carbohydrates- what is the function of lactose in animals?

A sugar found in the milk of mammals, provides energy for sucking infants

13

Carbohydrates- what is the function of glycogen in animals?

Used by animals for short term energy storage (between meals) in the liver

14

Carbohydrates- what is the function of fructose in plants?

Found in honey and onions, very sweet and good source of energy

15

Carbohydrates- what is the function of sucrose?

Used primarily as a transportable energy form (e.g sugar beets and sugar canes)

16

Carbohydrates- what is the function of cellulose?

Used by plant cells as a strengthening component of the cell wall

17

Carbohydrates- when does condensation (dehydration) reactions occur?

When molecules are covalently joined together and water is formed as a by- product

18

In carbohydrates what is the bond that is formed via condensation reactions called?

Glycoside linkage

19

What is a condensation reaction?

Is hydrolysis re reaction which requires a water molecule to break a covalent bond between 2 sub units

20

Carbohydrates- When a single monomer joins what is it called?

Disaccharide

21

Carbohydrates- when a sugar contains multiple subunits (more than 10) what are they called?

Polysaccharide

22

Draw condensation reaction matey

Do it Martha.

23

Lipids- what are they?

Group of organic molecules that are insoluble in water but soluble in non- polar solvents

24

What are 3 examples of lipids?

Triglycerides (fats and oils), phospholipids, steroids

25

Lipids- what does saturated mean?

No double bond

26

What does unsaturated mean?

Double bond

27

Draw the general structure of a lipid, a saturated lipid and a unsaturated lipid

Do it Martha.

28

Lipids- what does condensation reaction occur between?

3 hydroxyl groups of glycerol and the carboxyl groups of 3 fatty acids.

29

Lipids- what does the condensation reaction form?

Forms a triglyceride bond ( and 3 molecules of water)
