Triestered

Triestered refers to a chemical compound that has undergone esterification on three hydroxyl groups. In organic chemistry, an ester is a functional group that can be formed from the reaction of an alcohol and a carboxylic acid. When a molecule possesses three hydroxyl (-OH) groups, and each of these groups reacts with a carboxylic acid or its derivative to form an ester linkage, the resulting compound is called a triestered.

Common examples of triestered compounds include triglycerides, which are esters of glycerol (a triol) and fatty acids. Triglycerides are the main constituents of body fat in humans and animals, as well as vegetable fat. Another example is triacetin, which is the triestered form of glycerol with acetic acid. Triacetin has various applications, including as a plasticizer, a solvent, and in food products. The properties of a triestered compound are significantly influenced by the nature of the alcohol and the carboxylic acids involved in its formation. The ester linkage is susceptible to hydrolysis, breaking down into the original alcohol and carboxylic acid under acidic or basic conditions, or with enzymatic action.
