carbs

A carbohydrate is a sugar (saccharide) or a sugar derivative. For the simplest carbohydrates, the carbon-to-hydrogen-to-oxygen atomic ratio is 1:2:1, i.e. they are often represented by the empirical formula (CH2O)n. Together with amino acids, fats, and nucleic acids, the carbohydrates are one of the major families of biomolecules. Read more on Wikipedia
