Lactone

A lactone is a cyclic ester, a type of lactide, which is formed from dehydrated lactic acid. ❋ Steve Carper (2008)

'celloxin' C_ {6} H_8 {O} _ {6} with 1-4 mols. unaltered cellulose; and the former they particularly refer to as a lactone of glycuronic acid. ❋ C. F. Cross (N/A)

To communicate with its brethren, it uses a molecule called acyl-homoserine lactone, or AHL. ❋ Unknown (2009)

A true challenge indeed, when you cannot use Benzyl acetate; not to mention (E)-ocimene, linalool, asmine lactone, or gamma-decalactone (used to create gardenia headspace). ❋ Ayala Sender (2008)

In addition to the generic nutty notes of the pyrazines, one study found a lactone octalactone that is also present in coconuts. ❋ Harold McGee (2004)

Angelica Angelica is a large, rangy plant of northern Europe, Angelica archangelica, that has fresh, pine, and citrus notes, but is dominated by a sweet-smelling compound called the angelica lactone. ❋ Harold McGee (2004)

The natural antibiotic, cephalosporin C, loses on hydrolysis an acetyl group to give the more stable Cc molecule with the carboxyl group combined in a five-membered lactone ring. ❋ Unknown (1964)

But by the 1970s it was known that the lethal chemical, first called qinghaosu and now artemisinin, had a structure never seen before in nature: In chemical terms, it is a sesquiterpene lactone with a peroxide bridge. ❋ Unknown (2012)

To ensure that there is no interference from the most recent deworming, FECRT should not be performed within eight weeks following the last benzimidazole or pyrimidine treatment, or within 12 (ivermectin) or 16 (moxidectin) weeks after a macrocyclic lactone treatment. ❋ By (2010)

In their system, a promoter DNA sequence (P luxI) drives the production of LuxI, an enzyme that synthesizes the quorum-sensing signal acyl-homoserine lactone (AHL). ❋ Martin Fussenegger (2010)

E. coli genomes, including in K-12 where they were shown to be involved in repression of homoserine lactone synthesis. ❋ Zhemin Zhou Et Al. (2010)

Dow sells several of the fermentation-derived macrocyclic lactone insecticides under the ❋ Unknown (2010)

The thermochromic dye is usually a mixture of a leuco dye (a dye whose molecules can take on two forms, one colorless; Hypercolor shirts often used crystal violet lactone), a weak acid, and a dissociable salt dissolved in the fatty alcohol 1-dodecanol. ❋ Matt Soniak (2010)

At warmer temperatures (> 75.2 °F), the salt dissociates, the pH is lowered, and the dye's lactone ring opens, allowing the dye to become colored, producing a color change in the warmed area. ❋ Matt Soniak (2010)
