lactone

The lactone ring is unstable and opens in basic media.

It is derived from mannopine through the formation of a lactone.

However, an N-oxime side chain is attached to the lactone ring.

The purple bubble uses a chemical called crystal violet lactone.

They are often terminated with a lactone or butenolide.

Both molecules include a lactone and a triple-repeating sugar called a glycoside.

Primary alcohol 2.1 was protected in preparation for lactone reduction in 2.3.

Each dye molecule in Zubbles is a structure known as a lactone ring.

This arrangement also became uncertain because of the sesquiterpene lactone chemistry in certain species.

The lactone is a versatile intermediate in organic synthesis.

However, subjecting the lactone ring to air, water or pressure, causes the ring to open.

Roxithromycin is derived from erythromycin, containing the same 14-membered lactone ring.

The peptidic ring is closed with an ester bond (lactone).

The acid exists in equilibrium with the lactone.

Kavalactones are a class of lactone compounds found in the kava shrub.

It is a macrolide lactone and acts by inhibiting calcineurin.

The unusual lactone hydrates 1.9 and 1.10 were isolated as synthetic intermediates in this process.

In an acidic environment, the lactone ring is broken, with the oxygen detaching from the central carbon.

The steroid core is connected with a lactone ring and a sugar part (see figure 1 in Prassas).

The plant is somewhat toxic to mammals and insects due to the presence of the lactone tenulin.

Galanolactone is a diterpenoid lactone first isolated from ginger.

The lactarane-type sesquiterpene lactone 15-hydroxyblennin A is one of several sesquiterpenes produced by the species.

It was discovered several years later by Guth in white wines and was named "wine lactone".

One example of a (organic) lactone is gamma-valerolactone.

It is a lactone with coconut-like odor.
