This study focused on the preparation method of antioxidant peptides by enzymatic hydrolysis of bone collagen after microwave assisted acid pre-treatment and nitrogen protection. Phosphoric acid showed the highest ability of hydrolysis among the four other acids tested (hydrochloric acid, sulfuric acid and/or citric acid). The highest degree of hydrolysis (DH) was 9.5% using 4 mol/L phosphoric ...

Increased fisheries products have raised by-products that are discarded due to low economic value. In addition, marine still rich in protein and nutritional value biological activities give benefits human health. Meanwhile, there is pressure for sustainability practices industries reduce waste minimize the detrimental effect on environment. Thus, valorization through bioactive peptide mining cr...

The kinetics of chemical hydrolysis including neutral, acid- and base-catalyzed hydrolysis of 4-methylumbelliferyl caprylate (MUCAP) salmonella reagent were studied at different temperatures. The rate constants and activation parameters were determined by following the build-up of fluorescence peak of the hydrolysis product 4-methylumbelliferone (4-MU). The time scale of esterase enzyme hydroly...

Extensive kinetic study has been carried out on the hydrolysis of mono-2,6-dimethylphenyl phosphate ester in acid 0.1 to 6.0 mol. dm.HCl and buffers from 1.24 to 7.46 pH at 97± 0.5°C in water. Systematic ionic data proves the presence of acid catalyzed hydrolysis. The monoester has been found to be hydrolysis by conjugate acid, mono-negative, neutral and di -negative species. The inorganic phos...

The metabotropic glutamate 1a (mGlu1a) receptor is a G protein-coupled receptor linked with phosphoinositide (PI) hydrolysis and with β-arrestin-1-mediated sustained extracellular signal-regulated kinase (ERK) phosphorylation and cytoprotective signaling. Previously, we reported the existence of ligand bias at this receptor, inasmuch as glutamate induced both effects, whereas quisqualate induce...

Gadam sorghum stalks are agricultural residues which can be hydrolyzed into fermentable sugars that used to produce bioethanol is a renewable source of energy. In order from lignocellulosic biomass such as stalks, several processes including hydrolysis involved. However, the use for production hindered by low yield obtained during hydrolysis. The lack sufficient information on optimal condition...
