Lactones are usually named according to the precursor acid molecule (aceto = 2 carbon atoms, propio = 3, butyro = 4, valero = 5, capro = 6, etc.), with a -lactone suffix and a Greek letter prefix that specifies the number of carbon atoms in the heterocycle — that is, the distance between the relevant -OH and the -COOH groups along said backbone.The first carbon atom after the …

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.

Lactone is derived from a compound called Lactide, that is generated by the dehydration of lactic acid. It has a ring of 2 or more carbon atoms and 1 oxygen atom. Explore more @ BYJU'S.

A lactide is simply a form of lactone, which can be derived from lactic acid by heating. The chemical formula of a lactide is C 6 H 8 O 4 . In contrast, the lactone is a cyclic ester derived from hydroxy acid.

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.

2021年3月26日 · Lactone family have received considerable attention from the scientific community. Abstract This review summarizes the current knowledge on lactones, a class of biologically active natural products isolated from a wide range of living organisms.

Lactones are present in most expressed oils and tend to end in -lactone or -ine. The percentage of lactones present may be low, but they play an important role as expectorants and mucolytics. However, lactones tend to have the same potential neurotoxic effects as ketones.

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.

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 ).

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.
