애플리케이션

Propionic anhydride can be used as an acylating agent for the lipase-catalyzed esterification of alcohols. Recent studies indicate that the particle boards manufactured from wood chips modified with propionic anhydride show enhanced dimensional stability.

Polyethylenimine (750 kDa) has been derivatized to influence the proton sponge mechanism and hydrophobic-hydrophilic balance. The polymer was acylated using acid anhydrides of varying carbon chain length, followed by cross-linking with PEG-bis-P to form compact nanoparticles. The chemical linkages in

Polyethylene glycol (PEG)-conjugated therapeutic peptides/proteins have been shown to exhibit clinical properties superior to those of their corresponding unmodified parent molecules. However, the desirable pharmacological features gained by protein PEGylation become irrelevant if conjugates are inactivated or cannot reach their

In eukaryotic cells, posttranslational modifications (PTMs) on histones regulate chromatin structure and thus impact nearly all chromatin-templated events, including replication, transcription, and DNA repair. During S phase, newly synthesized histones are deposited onto DNA, leading to dilution of total chromatin-associated
