WebOct 8, 2024 · In initial assays the non-specific β-glucosidase substrate p -nitrophenyl-β- D -glucopyranoside (pNPG) was used. For that, 500 μL of enzyme extract in 10 mM phosphate buffer at pH 7.1 were incubated with 500 μL 5 mM aqueous pNPG at 25°C for 5 min. WebAbstract. In the current study, we investigated the inhibitory activity of water soluble ${\beta}-glucan$ from oat (Avena sativa) against various digestive enzymes such as ${\alpha}-glucosidase$, sucrase, maltase and glucoamylase.Inhibition of these enzymes involved in the absorption of disaccharide can significantly decrease the post-prandial …
