Organic molecules are substances found in living things, the four main classes are carbohydrates, proteins, lipids, and nucleic acids.
The original definition of organic chemicals were ones that could only be made by living things (organisms, thus the name) never in a lab. Then chemists gradually learned how to make a few of them. The definition was changed to complicated compounds containing the element carbon. This usually requires a minimum of 2 carbon atoms per molecule. Now we can make many of them in industrial quantities. An organic molecule are built around chains of carbon atoms and are the molecules of life. The four main groups of organic molecules are proteins, nucleic acids, lipids, and carbohydrates.
Your body, as a whole, is one organism. However, many, many parts make up that whole. As you consider the various levels of the body (see Figure 1), you understand that a large number of parts are within parts. It's akin to looking at a pine tree. At first, you notice the entire tree - a whole organism. However, as you look closer, you notice the branches. Looking at the twigs on the branches, you notice each needle on the twigs. Thousands, if not millions, of needles exist on that one single pine tree. The same analogy holds for the human body or the body of any animal. First, you notice the entire body. Next, you see that the entire body is made up of parts and organs, and each of those organs is made up of a variety of tissues. And if, as a pathologist does, you examine a magnified sample of one of the human body's tissues under a microscope, millions of cells become visible. Yet you can turn up the magnification for an even closer look: Cells contain molecules that are made up of even smaller components called atoms.
