What does Ac stand for?

Removal of the Acetyl Group From the Poly(NPMA-co-NAMI) About 9.

The formulation also contains an anti-soil redeposition component that prevents resoiling of hydrophilic fibers and hydrophobic fibers when coexisting with said inorganic salt, which is a water-soluble polymer substance of a nonionic system including at least one species selected from the group consisting of an acetyl group, methoxy group, hydroxypropyl group, and poly-oxy propylene group as the hydrophobic group, and including a hydroxyl group as the hydrophilic group.

Sir2 removes an acetyl group attached to a specific site (lysine at position 16 or K16) on histone H4-histones are proteins that package and organize the long strands of DNA within the nucleus and also are central regulators in turning genes on and off.

Only two flavone glycosides having an acetyl group at position 4' have previously been reported from plants; these compounds are apigenin 7-O-glucoside 4'-p-coumarate identified by Petrenko (Khim.

In one of the new studies, Sassone-Corsi's group shows that SIRT1 acts as tick to CLOCK's tock, removing an acetyl group from histones and also from CLOCK's partner BMAL1.

In the new study, Sassone-Corsi's group shows that SIRT1 indeed acts as tick to CLOCK's tock, removing an acetyl group from histones and also from CLOCK's partner, BMAL1.

The (13)C CP/MAS data suggest that most of the lignin has been removed by the oxone oxidation treatments, more so for the alkaline-washed samples, where acetyl groups (methyl carbon at 21 ppm and carbonyl carbon at 173 ppm) on hemicelluloses have also been removed.

One way for cells to accomplish this task is by attaching a special chemical group, called an acetyl group, to the proteins.
