Carboydrate is the greatest energy resources. And almost in the world, especially in developing countries around 80% using carbohydrates as resources energy, and 20% using proteins and greases.
When :
1 gram carbohydrate will produce energy equivalent 4,5 calories
1 gram protein will produce energy equivalent 4,5 calories
1 gram grease will produce energy equivalent 9 calories
Carbohydrate is used as energy recources caused :
1. easy looking for/ much in nature
2. easy cultivationing
3. the cost is cheap relative.
In nutrient science, carbohydrate can be classified in 3 class :
1. Monosakarida is simple sugars that containing 1 unit sugar
Example : a. Glukosa ( grape sugar)
b. Fruktosa (fruit sugar)
c. Galaktosa and Manosa (milk sugar)
characteristics :
- easy soluble in water
- can be crystaled
- have sweet taste
2. Disakarida is carbohydrate that containing 2 unit monosakaridas
Example : a. Sukrosa (sand sugar)
b. Laktosa (milk sugar)
c. Maltosa (malt sugar)
characteristics :
- have sweet taste
- soluble in water
3. Polysakarida is carbohydrate that containing much unit sugars.
Example : Sellulosa, Pektin, Jelly, Gum
Characteristics :
- have molecule heavy that great
- It wasn’t be crystaled
- Have no sweet taste
- Can’t soluble in water
- Have various absorbed ability
The benefit of carbohydrates are :
1. as energy recources
2. economical proteins as energy recources
3. manage grease metabolism
4. help fasting absorbed process.
