They are made from many carbon atoms. A molecule is said to be organic if it contains carbon atoms (C) linked to hydrogen atoms (H). The organic molecules can be distinguished during a combustion since the carbon atoms will turn into carbon dioxide (CO2) and the hydrogen atoms into water (H2O).
A molecule of the kind normally found in living systems. Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.
