The name lactone derives from the ring compound called lactide, which is formed from the dehydration of 2-hydroxypropanoic acid (lactic acid) CH 3 -CH (OH)-COOH.

Lactone, any of a class of cyclic organic esters, usually formed by reaction of a carboxylic acid group with a hydroxyl group or halogen atom present in the same molecule.

Jul 31, 2025 · Various catalysts and reaction conditions can be employed to facilitate this ring-closing reaction, influencing the efficiency and yield of the specific lactone formed. Once formed, lactones …

A lactone is a cyclic ester formed from a single molecule of a hydroxy acid. In contrast, a lactide is a cyclic di-ester formed from two molecules of a hydroxy acid (like lactic acid) reacting with each other.

Because lactone formation is enhanced during heating, some of the raisined character of sunburned grapes may come from lactones, notably 2-pentenoic acid-γ-lactone.

The meaning of LACTONE is any of various cyclic esters formed from hydroxy acids.

A lactone or cyclic ester is a carboxylic acid ester in the molecule of which the ligand on the carbonyl carbon and that on the oxygen atom are linked by one or more carbon chains.

A lactone is a cyclic ester formed by the intramolecular condensation of a hydroxycarboxylic acid, resulting in the elimination of water. These compounds are characterized by a ring structure that …

The name lactone derives from the ring compound called lactide, which is formed from the dehydration of 2-hydroxypropanoic acid (lactic acid) CH 3 -CH (OH)-COOH.

Some higher lactones are very useful in daily uses. For instance, erythromycin is a 14-membered lactone used as an antibiotic. Lactones are generally named by several acid groups present along …
