Organic chemistry is the study of the properties of the compounds of carbon that are organic. All carbon compounds except for a few inorganic carbon compounds are organic. Inorganic carbon compounds include the oxides of carbon, the bicarbonates and carbonates of metal ions, the metal cyanides, and a few others.
Biochemistry is the study of the chemicals of living systems and their interactions. Alone, these chemicals are not living, but together, their interactions work together to create and sustain a living organism. The reactions between them obey all of the known laws of chemistry. To sustain a living system, materials, energy, and information is needed. The substances that supply these three necessities are the basic materials which, together with water and a few kinds of ions, make up cells and tissues. Proteins are the main source of the materials. Lipids and carbohydrates are the major sources of the chemical energy needed to maintain function. And information is carried in a genetic code by molecules of nucleic acid. This section will not be very in depth because many aspects extend into the field of biology.
