Modification reactions may involve the addition of a phosphate or acetyl group onto the sugars, or the addition of new sugars, such as neuraminic acid.

HAT molecules facilitate the transfer of an acetyl group from a molecule of Acetyl Coenzyme-A ( Acetyl-CoA ) to the NH3 + group on Lysine.
43.
When a Lysine is deacetylated, factors known as Histone Deacetylases ( HDACs ) catalyze the removal of the acetyl group with a molecule of H2O.
44.
Generally, in cabinets or display cases that are entirely or partially made of wood, the hydrolysis of acetyl groups in the wood hemicelluloses creates acetic acid.
45.
The acetyl group is removed by one of the HDAC enzymes during deacetylation, allowing histones to interact with DNA more tightly to form compacted nucleosome assembly.
46.
It is believed that NAC is deacetylated ( loses its acetyl group ) and transforms into carnosine, which then acts as an antioxidant and against glycation.
47.
More recent studies have found that postmortem brain tissue from schizophrenic patients had higher levels of HDAC, histone deacetylase, an enzyme that remove acetyl groups from histones.
48.
The chromatin material, far from having chemical groups added to it, emerged lighter than before, and the difference in weight corresponded exactly to acetyl groups being removed.
49.
It is closely related to the natural alkaloid colchicine with the replacement of the acetyl group on the amino moiety with methyl, but it is less toxic.
50.
In addition, treatment of DLC1 downregulated tumor cell lines with a histone deacetylase inhibitor prevents histone deacetylase ( HDAC ) enzymes from removing acetyl groups from specific histones.
