1

What are the functions of protein?

- helps you grow
- repairs body if damaged
- maintains body to keep it working well
- gives body energy

2

What are Proteins?

Proteins are very big molecules and are made of smaller units called amino acids.

3

Define High Biological Value

Protein foods that contain all the essential among acids are said to be HBV.

4

Define Low Biological Value

Protein foods that are missing one or more essential amino acids are said to have LBV.

5

Sources of HBV?

Milk, meat, eggs, fish, cheese

6

Sources of LBV?

Nuts and seeds, cereals, pulses and beans.

7

Where is ovalbumin found?

Egg white

8

Where is gluten found?

Wheat

9

Where is collagen found?

Meat

10

Where is caseinogen found?

Cheese

11

Milk

12

What happens to extra protein if it is not used?

It is stored as fat.

13

What happens if a child doesn't have enough protein?

- stop growing
- hair becomes thin
- cannot digest food
- have diarrhoea
- infections
- thin and weak

14

What happens if a adult doesn't have enough protein?

- become thin
- internal organs become weak
- hair and skin becomes dry
- they get oedema


15

What is fat molecules chemically known as?

Triglyceride
- 1 part glycerol
- 3 part fatty acid

16

Why we need fat?

- stored as energy
- stored under skin as adipose tissue which is insulating and protects bones

17

What happens if fat is not soluble?

If it gets oxidised with free radicals, it will get deposited in arteries - leading to fatty plague and heart attack

18

What happens if there is too much fat?

- obese
- cholesterol
- heart attack

19

What happens if there is too little fat?

- thin bones are easily breakable
- slow growth rate

20

- Fructose ( from plant juices, honey, fruits)
- Glucose (vegetables, fruits, sugar used in cooking)
- Galactose ( milk)

24

Double sugars:
How is sucrose made and what foods supply them?

Unit of glucose and fructose
-found in sugar cane, brown/caster/granulated sugar

25

Double sugars:
How is Lactose made and what foods supply them?

Unit of glucose and galactose
- found in milk and some milk products like yoghurt

26

Double sugars:
How is Maltose made and what foods supply them?

Unit of glucose and glucose
- found in cereal plants, barley, malted drinks

27

Give five examples of complex sugars

It is the main energy source for plants.

30

What is the main function of NSP- dietary fibre?

It gives plants its structure.
