Examples of Organic Compounds

An organic compound has molecules that contain covalently bonded carbon and hydrogen atoms. They can contain additional elements. Some occur naturally, while others are synthesized in a laboratory setting. These compounds can be gaseous, liquid or solid. There are four primary categories of organic compounds. Discover examples of organic compounds along with their molecular formulas.

Many organic compounds are carbohydrates. The chemical formula for carbohydrate is (CH2O)n. In this formula, “n” represents the number of carbon atoms in the molecule. There are three categories of carbohydrates: monosaccharides, disaccharides and polysaccharides.


Carbohydrates in the monosaccharides category are simple sugars. Many, but not all, have the molecular formula (C6H12O6).

  • fructose (C6H12O6)
  • glucose (C₆H₁₂O₆)
  • allose (C₆H₁₂O₆)
  • altrose (C₆H₁₂O₆)
  • galactose (C₆H₁₂O₆)
  • gulose (C₆H₁₂O₆)
  • arabinose (C5H10O5)
  • erythrose (C4H8O4)


Disaccharides are pairs of monosaccharides, meaning they are two simple sugars. These examples are formed by joining together two monosaccharides with a chemical formula of (C6H12O6), so they have the same molecular formula (C₁₂H₂₂O₁₁).

  • lactose (C₁₂H₂₂O₁₁) - includes glucose and galactose
  • sucrose (C₁₂H₂₂O₁₁) - includes glucose and fructose
  • maltose (C₁₂H₂₂O₁₁) - made up of two glucose molecules joined by a band
  • trehalose (C₁₂H₂₂O₁₁) - made up of two glucose molecules; also called tremalose or mycose
  • melibiose (C₁₂H₂₂O₁₁) - includes glucose and galactose
  • cellobiose (C₁₂H₂₂O₁₁) - formed from two glucose molecules


Polysaccharides are a group of carbohydrates that contain multiple monosaccharides. They can be monomers (single molecules) or polymers (multiple molecules that have bonded together) of sugars. Starches are included in this category.

  • glycogen (C6H10O5)n
  • cellulose (C6H10O5)n
  • amylose (C6H10O5)n
  • xanthan gum (C35H49O29)
  • carrageenan (C24H36O25S2-2)
  • alactomannan (C18H32O16)


A lipid is a fatty or waxy organic compound. They are predominantly made up of hydrocarbons. There are dozens of lipids, many with extremely complicated molecular formulas.

  • triglycerides - glycerol (C3H8O3) paired with fatty acids; there are many types of triglycerides with varying molecular formulas, including saturated, unsaturated and trans fats
  • diglyceride (C43H68O5)
  • monoglyceride citrate (C9H14O9)
  • phosphoglycerides (CH2OH–CHOH–CH2OH)
  • glycerides (C16H32O4)
  • ceramide (C36H71NO4)
  • archaeol (C43H88O3)
  • aaldarchaeol (C86H172O6)
  • Intralipid (C60H115NO10P+)


Proteins are extremely complex. All organs and tissues contain proteins, which are molecules with polymers of amino acids held together with peptide bonds. Proteins are made up of amino acids. In addition to carbon and hydrogen, they also contain nitrogen and oxygen.

  • insulin (C257H383N65O77S6)
  • collagen (C65H102N18O21)
  • elastin (C27H48N6O6)
  • keratin (C28H48N2O32S4)
  • oxytocin (C43H66N12O12S2)
  • thrombin (C12H10ClN3S)
  • actin (C25H34ClN5O6)


Nucleotides are organic compounds that contain a nitrogen base, ribose or deoxyribose (monosaccharides that have five carbon atoms), at least one phosphate group, and hydrogen. All but one of the nucleotides are nucleic acids. Adenosine triphosphate is also a nucleotide.

Nucleic Acids

Nucleic acids are necessary for all forms of life. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are examples of nucleic acids. Examples of modified nucleotides, which make up nucleic acids, include:

  • inosine (C10H12N4O5)
  • pseudouridine (C9H12N2O6)
  • queuosine (C17H23N5O7)
  • dihydrouridine (C9H14N2O6)
  • wybutosine (C21H28N6O9)
  • 3-methylcytidine (C10H15N3O5)
  • 5-methylcytidine (C10H15N3O5)
  • 2-thiouridine (C9H12N2O5S)
  • 4-thiouridine (C9H12N2O5S)

Adenosine Triphosphate

Adenosine triphosphate (C10H16N5O13P3), commonly referred to by the acronym ATP, is where the energy used and stored by cells comes from. The phosphates in ATP store potential energy, so it is described as a “high energy” organic compound.


Organic Compounds Are Everywhere

These are a few examples of the many, many organic compounds that exist. These compounds are at the heart of organic chemistry, which is “the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds.” They play a role in every aspect of life. There are millions and millions of known organic compounds, and probably more that have yet to be discovered or identified.

Expand Your Chemistry Knowledge

Whether you’re a student taking a general chemistry class or one focused specifically on organic chemistry, chances are that you need to be able to list or identify at least some organic compounds. Now that you have reviewed what an organic compound is, some examples of organic compounds in different categories, and their chemical formulas, it’s a great time to expand your chemistry knowledge in other ways.

Start by exploring 20 common examples of bases in everyday life. If that isn’t quite challenging enough, explore some examples of catalysts. The more you learn now, the better prepared you’ll be for your next chemistry class, or even a professional career working as a chemist or in another science-related occupation.
