Chemical Constituents of Cells

The chemicals that enter into metabolic reactions or are produced by them can be divided into two large groups. Generally, those that contain carbon and hydrogen atoms are called organic (or-gan'ik); the rest are called inorganic (in"or-gan'ik).

Inorganic substances usually dissolve in water or react with water to release ions; thus, they are electrolytes. Many organic compounds also dissolve in water, although as a group they are more likely to dissolve in organic liquids such as ether or alcohol. Organic compounds that dissolve in water usually do not release ions and are therefore called nonelectrolytes.
