Lactone - Wikipedia
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. Lactic acid, in turn, derives its name from its original isolation from soured milk (Latin: lac, lactis).
Lactone | Aromatic, Cyclic, Ring Structure | Britannica
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.

2024年12月3日 · Lactones are generally named after the carboxylic acid by using the suffix-lactone. A Greek letter is used to indicate the ring size. Thus, all γ-lactones have five-membered rings and all ε-lactones have seven-membered rings.
Lactones: What are They? How Are They Made? - Quirky Science
Engineering more complicated lactone structures requires involves reverse thinking – imagining the product, then going backwards to the starting materials. Pendant groups may be added in this way. For instance, the number 3 carbon could have one of its hydrogen atoms replaced by a methyl group ( -CH₃ ).

2022年2月28日 · 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.
Lactone - an overview | ScienceDirect Topics
It is a condensation product of an alcohol group and a carboxylic acid group in the same molecule of hydroxycarbonic acid. The most stable structures are the five-membered (gamma-lactone) and six-membered lactones (delta-lactone). Lactones can be produced commercially by biotechnological means using yeasts.
