The simplest organic molecules, hydrocarbons, contain only hydrogen atoms bonded to a carbon backbone. The carbon backbone ranges from one carbon atom in methane, or natural gas, to thousands of carbon atoms, such as in polyethylene, a commonly used plastic.
Regarding this, what does an organic compound always contain?
Most organic compounds contain carbon, hydrogen, and sometimes other elements such as nitrogen, sulfur, oxygen, or phosphorus.
What element must be in an organic compound?
Proteins. Proteins, among the most complex of all organic compounds, are composed of amino acids (see Figure 2-4), which contain carbon, hydrogen, oxygen, and nitrogen atoms. Certain amino acids also have sulfur atoms, phosphorus, or other trace elements such as iron or copper.
What do organic compounds consist of?
Lipids are organic compounds that consist of carbon, hydrogen, and oxygen. They are made up of fatty acids and other compounds. They provide cells with energy, store energy, and help form cell membranes. Proteins are organic compounds that consist of carbon, hydrogen, oxygen, nitrogen, and, in some cases, sulfur.
