# What atoms are found in carbohydrates?

Apr 10, 2014

The term "carbohydrate" tells us what they are made of - carbon, hydrogen and oxygen.

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.
