Yesterday, I just learnt about Nutrition at school. In text book, it is said that CArbohydrates are needed because :

1. As a source of energy
2. To form supporting structure, e.g. Cellulose cell walls in plants
3. To be converted to other organic compounds such as amino acids
4. For the formation of nucleic acids, e.g. DNA

As I know, our body has an enyzme called amylases which break down carbohydrates into glucose. From the function of carbohydrates given above, my question is how does our body convert carbohydrates into amino acids and why must the body convert it?

The body does NOT use carbohydrates as a source to make amino acids. The ten or so essential amino acids we need in or diet are made by plants and microorganisms...we can only get them in our diet by eat either a plant or animal. The other nonessential amino acids are "transaminated" from the ess Entail amino acids.
