What is the difference between hydrocarbons and carbohydrates?

In: Chemistry

Oxygen. Hydrocarbons are pure carbon + hydrogen, while carbohydrates contain oxygen as well. Hydrocarbons are also *engine* fuel and used in industry, while carbohydrates are *people* fuel (i.e. food) and used in biochemistry. Also, to be considered a carbohydrate, the molecule must have 2x or more the amount of hydrogen as oxygen.

Since you picked Chemistry, hydrocarbons have carbon and hydrogen atoms only, where carbohydrates also have oxygen atoms.

Carbon atoms can form many shapes, and both hydrocarbons and carbohydrates are generally long string molecules without rings.

Hydrocarbons – carbon and hydrogen

Carbohydrates – carbon, hydrogen and oxygen
