# What atoms are found in carbohydrates?

The carbon is "hydrated" - or joined with water. This means that there is a very special ratio of 2 hydrogens to every 1 oxygen within a carbohydrate. For example, the formula for sucrose is ${C}_{12} {H}_{22} {O}_{11}$.
The general formula for a carbohydrate is ${C}_{m} {\left({H}_{2} O\right)}_{n}$, where m and n may be different.
