what are  things  that organic molecules contain
Organic molecules can contain hundreds or even thousands of atoms that can be arranged in many ways. The table above compares the four groups of organic compounds that make up all living things – carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates Carbohydrates are organic molecules that supply energy for cell processes. Sugars and starches are carbohydrates that cells use for energy. Some carbohydrates also are important parts of cell structures. For example, a carbohydrate called cellulose is an important part of plant cells. Lipids Another type of organic compound found in living things is a lipid.
To keep it simple, remember it this way: organic compounds always contain carbon and hydrogen (and maybe some other elements), inorganic compounds do not contain carbon and hydrogen together. Organic compounds are found in living things, their wastes, and their remains.ehydration Synthesis vs Hydrolysis : All of the organic compounds we will study are examples of polymers. A polymer is a large chemical compound composed of smaller repeating units --- over & over & over again. Like a long choo-choo train is made up of smaller connected, repeating, choo-choo cars.
