The name lactone derives from the ring compound called lactide, which is formed from the dehydration of 2-hydroxypropanoic acid (lactic acid) CH3-CH(OH)-COOH. Lactic acid, in turn, derives its name from its original isolation from soured milk (Latin: lac, lactis). The name was coined in 1844 by the French chemist … See more Lactones are cyclic carboxylic esters, containing a 1-oxacycloalkan-2-one structure (−C(=O)−O−), or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. See more Many methods in ester synthesis can also be applied to that of lactones. In one industrial synthesis of oxandrolone the key lactone-forming step is an organic reaction - esterification See more Flavors and fragrances Lactones contribute significantly to the flavor of fruit, and of unfermented and fermented dairy products, and are therefore used as … See more 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 See more Naturally occurring lactones are mainly saturated and unsaturated γ- and δ-lactones, and to a lesser extent macrocyclic lactones. The γ- and δ-lactones are intramolecular esters of the corresponding hydroxy fatty acids. They contribute to the … See more The most stable structure for lactones are the 5-membered γ-lactones and 6-membered δ-lactones because, as in all organic cycles, 5 and 6 membered rings minimize the strain of See more • β-propiolactone • γ-butyrolactone (GBL) • D-glucono-δ-lactone (E575) • ε-caprolactone • Macrolides • Kavalactones See more WebLactide: 60/170: Polyhydroxyalkanoate: Carbohydrates: 4/180: Polybutylene adipate-terephthalate: Carbohydrates: Succinic acid: 1,4-Butanediol –32/115: Carbohydrates: ... ppp or employee retention credit
