What is the Difference Between Phosphodiester Bond and Phosphoester Bond?
🆚 Go to Comparative Table 🆚Phosphodiester and phosphoester bonds are both chemical linkages found in biochemical molecules. However, there are some differences between them:
- Type of molecules: Phosphodiester bonds are found in nucleic acids like DNA and RNA, where they form the backbone of the molecules. Phosphoester bonds, on the other hand, are found in phosphoglycerides and occur when the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules.
- Number of ester linkages: The prefix "di-" in phosphodiester refers to the fact that this type of chemical bond has two ester linkages per phosphodiester bond. Phosphoester bonds have only one ester linkage.
Despite these differences, the two terms are sometimes used interchangeably for introductory biology classes, as both are chemical linkages.

Comparative Table: Phosphodiester Bond vs Phosphoester Bond
Phosphodiester bonds and phosphoester bonds are both biochemical bonds that play crucial roles in various molecules. Here is a table summarizing their differences:
Feature | Phosphodiester Bond | Phosphoester Bond |
---|---|---|
Structure | Consists of two ester linkages per phosphodiester bond | Consists of a single ester linkage |
Formation | Forms when two hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules | Forms when a hydroxyl group in phosphoric acid reacts with a hydroxyl group on another molecule |
Function | Central to all life on Earth, forming the backbone of DNA and RNA molecules | Found in phosphoglycerides and phosphorylated alcohols |
Examples | DNA and RNA molecules | Phospholipids and proteins |
Phosphodiester bonds are the backbone of DNA and RNA molecules, linking the third carbon atom of a sugar molecule (deoxyribose in DNA and ribose in RNA) with the fifth carbon atom. On the other hand, phosphoester bonds are found in phosphoglycerides and phosphorylated alcohols.
