Cellulose is a polyol and thus susceptible to acetylation, which is achieved using acetic anhydride. Acetylation disrupts hydrogen bonding, which otherwise dominates the properties of cellulose. Consequently, the cellulose esters are soluble in organic solvents and can be cast into fibers and films. [12]
Most of the acetylation occurs on the N-terminal tail which protrudes out of the nucleosome (Fig. 1; Kimura et al., 2005; Choi and Howe, 2009). Acetylation serves to neutralize the positive charge of lysine, and thus helps decondense the chromatin facilitating access to the transcriptional machinery.
As one of the typical representatives of non-histone protein acetylation, p53 acetylation broadens the scope of acetylation modification, providing an important basis for further studies on protein acetylation.
In chemistry, acetylation is an organic reaction in which an acetyl group (CH3CO-) is introduced into a molecule. This reaction typically involves the use of acetic acid (CH3COOH) or acetic anhydride (CH3CO)2O as the acetylating agent. The resulting product is called acetate.
Acetylation is a chemical reaction in which a hydrogen atom is substituted for an acetyl group (CH 3 C=O group) in a compound. The products formed in acetylation reactions typically have an acetoxy functional group.
Acetylation is a fundamental and widespread biological process. This biochemical modification involves adding a small chemical group to various molecules within cells.
Acetylation is any chemical reaction that adds an acetyl chemical group (CH3C=O, sometimes abbreviated in chemical structures as Ac) and is a type of acylation reaction.
Acetylation is the addition of a small chemical tag, known as an acetyl group, to a target molecule. In cellular biology, this process most frequently occurs when the acetyl group is attached to a protein, typically at a specific lysine residue.
