R)and (S)-hydroxypropyl-coenzyme M dehydrogenases (Rand S-HPCDH) are stereospecific enzymes that are central to the metabolism of propylene and epoxide in Xanthobacter autotrophicus. The bacterium produces Rand S-HPCDH simultaneously to facilitate transformation of Rand S-enantiomers of epoxypropane to a common achiral product 2-ketopropyl-CoM (2-KPC). Both Rand S-HPCDH are highly specific for ...

Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC a French fries coating to reduce oil uptake. This research aims study the utilization of OPEFB coating. consists two stages. The first stage is cellulose extraction and synthesis. synthesis through alkalization, methylation, propylation, neutralization. second use with different conce...

Nanoparticle Drug Delivery The encapsulation of nanoparticles in hydroxypropyl methyl cellulose is key to treat colorectal cancer through oral administration. In article 2202672 by Ilaria Rea, Hélder A. Santos, and co-workers, gelatin-coated diatomite loaded with galunisertib are functionalized an anti-L1-CAM antibody that targets metastatic colon cells. These then encapsulated a gastro-resista...

Porous polymer coatings are used to control drug release from pharmaceutical products. The coating covers a core and depending on the porous structure, different rates obtained. This work presents mass transport simulations performed ethyl cellulose films with porosities. were high spatial resolution 3D data obtained using focused ion beam scanning electron microscope. effective diffusion coeff...

BACKGROUND Derivatized celluloses, such as methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC), are of pharmaceutical importance and extensively employed in tablet matrices. Each batch of derivatized cellulose is thoroughly characterized before utilized in tablet formulations as batch-to-batch differences can affect drug release. The substitution pattern of the derivatized cellulose p...
