Evaluation of Antioxidant, Alpha-Glucosidase Enzyme Inhibitory and Antimicrobial Activities of Anthraquinone and Aloe-emodin
Background and Objectives: Aloe-vera is one of the most valuable medicinal plants in the world. The aim of this study was to evaluate the antioxidant, alpha-glucosidase inhibitory and antimicrobial properties of aloe-vera derivatives including aloe-emodin and anthraquinone. Materials & Methods: Antioxidant activity of aloe-emodin and anthraquinone was determined using ABTS method. Antimicrobi...
متن کاملThe inactivation of Bacillus subtilis alpha-amylase by N-acetylimidazole and tetranitromethane.
Bacillus subtilis oc-amylase is inactivated by treatment with N-acetylimidazole. Full catalytic activity is restored when the acetylated protein is treated with hydroxylamine. Spectral changes associated with the loss and recovery of activity indicate that exposed residues of tyrosine react. I f the enzyme is acetylated in the presence of substrate (soluble starch) the modified protein retains ...

abstract the first purpose of this study was to investigate the effect of consciousness-raising (c-r) activities on learning grammatical structures (simple present tense in this case) by iranian guidance school efl learners. the second one was to investigate the effect of gender on learning the simple present tense through c-r activities and tasks. finally, this study aimed to investigate the ...
Structural and functional differentiation of three groups of tyrosine residues by acetylation of N-acetylimidazole in manganese stabilizing protein.
To study its contribution to the assembly of the green plant manganese stabilizing protein (MSP) into photosystem II (PSII), tyrosine residues were specifically acetylated using N-acetylimidazole (NAI). In soluble MSP, three groups of Tyr residues could be differentiated by NAI acetylation: approximately 5 (actually approximately 5.2) Tyr residues could be easily acetylated (superficial), 1-2 T...
