Carbohydrates are organic molecules in which carbon (C) bonds with hydrogen and oxygen (H2O) in different ratios depending on the specific carbohydrate. ... All carbohydrates are made up of units of sugar.
Organic molecules can include things like carbohydrates, proteins, and fats. While organic molecules can have non-carbon atoms contained inside them, like oxygen, nitrogen, or even iron, they are mostly made of carbon and hydrogen chains. Because of this, they are made almost entirely of covalent bonds.
