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.
