Important as food, carbohydrate supply energy and IS used to make fats.

Is anybody here trying to make us feel guilty?

Why 'carbohydrate'? I thought 'carbohydrates' was a group of substances. No?

By the way, in your sentence, deepa, must be 'supplies'. It's a misprint, of course, but may be important.

Ok bubr! you are right. The carbohydrates is correct, and supplies too...

I has received a book

I have received a book!

By the way, Deepa, what do you think as a specialist about the problem of carbohydrates chirality? What is its cause? What sugar is better, with left or right chirality?

I too have some astrophysics questions to ask you, why do planets rotate while stars dont? I am serious! I think I should open an astronomy thread!!

Your answer is incorrect - 'carbohydrates' is a noun always used in the plural form and therefore the correct verb is 'are'

Sorry! Yes, I agree I was wrong, the moral of the story is I should never open EF when I am too sleepy! lol!
