Hello,
Release of energy after complete combustion of food is known as Gross Calorific Value.
- Carbohydrates have a gross calorific value of 4.1 kcal/g
- Proteins have a gross calorific value of 5.65 kcal/g
- Fats have a gross calorific value of 9.45 kcal/g
You can calculate gross calorific value in Laboratory using BOMB's Calorimeter.
The actual amount of energy liberated in the body from carbohydrates, proteins and fats is called Physiologic Value.
- Carbohydrates have a Physiological value of 4 kcal/g
- Proteins have a Physiological value of 4 kcal/g
- Fats have a Physiological value of 9 kcal/g
Physiological Value is exact value.
Significant difference can be seen between Physiological and Gross Value as Gross Value is measured using Lab equipments, there is a variation in reading or values.
Hope this was helpful.
