Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids (DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% by mass of nitrogen, the fourth most abundant element in the body after oxygen, carbon, and hydrogen.
Organic molecules are hydrocarbon molecules. There are four major types of organic molecules: Proteins, Lipids, Carbohydrates and Nucleic Acids. Organic molecules are mostly made of chains of carbon atoms with hydrogenâs attached. On the right, we see the basic structure of an organic or hydrocarbon molecule (C-H-C-H). A carbon atom has four electrons in its outer orbit and these four valence electrons are shared with other atoms.
