Aleuritic acid is a fatty acid that is commonly found in the resin of coniferous trees. It is also known as 9,10,16-trihydroxypalmitic acid and has a chemical formula of C21H38O5. Aleuritic acid is used in the production of lacquers, varnishes, and other coatings due to its high melting point and excellent film-forming properties.
Definitions
Aleuritic acid is a crystalline solid that is insoluble in water but soluble in organic solvents. It is a long-chain fatty acid that contains three hydroxyl groups and a carboxylic acid group. It is also known as 9,10,16-trihydroxypalmitic acid.
Origin
Aleuritic acid is primarily found in the resin of coniferous trees, such as pine and spruce. It is produced by the oxidation of abietic acid, which is a major component of coniferous resin. Aleuritic acid is also found in small amounts in the wax of some plants.
Meaning in different dictionaries

The same root words
Aleuritic acid is derived from the Greek word “aleuron,” which means flour. This is because aleuritic acid was first isolated from the flour of wheat bran. The root word “aleuron” is also the origin of the term “aleurone,” which refers to the outermost layer of a grain of wheat.
Example Sentences
- The high melting point of aleuritic acid makes it a popular choice for use in coatings.
- The antimicrobial properties of aleuritic acid make it a potential candidate for use in food preservation.
- The production of varnishes and lacquers often involves the use of aleuritic acid as a key ingredient.
