The presence of nitrogen, oxygen, and other atoms adds variety to these carbon molecules. Four important classes of organic molecules—carbohydrates, lipids, proteins, and nucleic acids—are discussed in the following sections.
Accordingly, what is considered an organic molecule?
Organic molecules are the molecules of life and are built around chains of carbon atoms that are often quite long. There are four main groups of organic molecules that combine to build cells and their parts: carbohydrates, proteins, lipids, and nucleic acids.
What is not an organic molecule found in living organisms?
These atoms' ability to attach to one another allows for the creation of innumerable compounds conducive to life. All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
What makes a molecule organic or inorganic?
In chemistry, organic means that a molecule has a carbon backbone with some hydrogen thrown in for good measure. Living creatures are made of various kinds of organic compounds. Inorganic molecules are composed of other elements. They can contain hydrogen or carbon, but if they have both, they are organic.
