What are the important functions of fat in the body?

Answer 1

makes them FATTT! umm that's a pretty terrible answer... it can but that's not really what it does, it doesn't function that way at all just people eat too much of the wrong sort of fats.

Fat is used for energy by the body it is the secondary energy source to be used after the bodys stores of carbohydrates have been depleted this starts happening about 20-60 minutes into physical exercise. it is also an insulation for the bodys organs, fat protects the body from cold weather.

It is also used as a median for the transport of fat soluable vitamins such as vitamin A D and K etc.

Consuming fat increases your satiety levels (feeling of fullness).

Polyunsaturated fat can infact reduce blood cholesterol which can be beneficial for many people so the message here is not to cut fat out but to eat more healthy monounsaturated and polyunsaturated fats and less saturated fats as these increase blood cholesterol. the guidelines for this is about 8-10% of daily energy should be from polyunsaturated fat, 10-20% energy should be from monounsaturated fat and less than 10%should be from saturated fat.

Answer 2

1. insulate and provide cushioning for body organs

2. provide efficient energy reserve (9 calories released per gram versus 4 for protein and carbohydrate)

3. participate in biochemical reactions as an intermediate

Answer 3

the main functions of fat in the body are providing energy to the body, help envelop the body from cold, quick changes in the temperature and cushion the body from bruises, strains, and breaks

Answer 4

there are loads:

1. Structural- phospholipids form bilayer that make up membranes of cells

2. Fuel -Oxidation of fatty acids releases ATP

3. Signalling - Lipids are precursors to messenger molecules such as prostglandins, leukotrienes and thromboxanes.

4. Insulation- adipose tissue prevents heat loss and can even generate heat through non-shivering thermogenesis (brown adipose tissue)

5. Nutrition- Certain vitamins can only be absorbed when they are dissolved in fats- fat soluble vitamins.

6. Endocrine function and Renewal- Adipocytes are broken down during lypolysis for hormone synthesis and contruction of new membranes.

Answer 5

Well when your starving your body uses fat up. That's why if somebody gets stranded or stuck as a POW they weigh a lot less than before because the body absorbed the fat.

Answer 6

Functions of fats are:

• To keep us warm.
• Give us more energy.
• Fats produce more than twice as much energy as the same amount as carbohydrates.

Answer 7

1) Most concentrated form of energy

2) Make up the cell membrane

3) Hormonal regulation

4) Enhance micronutrient absorption

5) Protection

Answer 8

good source of energy

good source of warmth
