The gastric phase of protein hydrolysis involves the proteolytic action of pepsin, which is secreted by the chief cells of the stomach as an inactive precursor called pepsinogen. This zymogene is activated by the acidic pH in the stomach lumen and by the autocatalytic hydrolysis of the active ...

This study presents a novel method for nanocellulose production using [Bmim]Cl as a green solvent, with enhanced hydrolysis efficiency achieved through the addition of a transition metal complex as a catalyst. The redox capability of the transition metal complex to break the glycosidic bonds in cell...
However, due to the differences between the two polymers, there are two main issues that need to be addressed in the acidic co-hydrolysis of polyester/cotton blends into TPA and HMF. One is to avoid the formation of undesirable byproducts from cotton in high concentrations of acid, such as...
Heterometallic metal-organic frameworks (MOFs) can offer important advantages over their homometallic counterparts to enable targeted modification of their adsorption, structural response, electronic structure, or chemical reactivity. However, controlling metal distribution in these solids still remains a challe...
Cellulose-specific CBM1 in AXE1 obviously contributed to its catalytic action against substrates compared with AXE1dC. However, replacement of CBM1 with xylan-specific CBM4-2 significantly enhanced AXE1 thermostability and catalytic activity against soluble substrate 4-methylumbelliferyl acetate. Whereas ...
A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed including an esterase or lipase enzyme, a source of hydrogen peroxide, and a functionalized ester substrate having the structure ##STR1## wherein R is a substituent having at ...
A method of phosphate ester hydrolysis including incubating a solution of an aqueous phosphate ester with a texaphyrin metal complex. The metal is a metal cation having catalytic activity for ester bo
Alkoxysilanes are hydrolyzed with water in the presence of various hydrolysis catalysts. The hydrolysis catalysts include the solid oxides of the Group IIa metals and solid acid catalysts. The solid a
