Many free radicals are generates in the human body due to metabolic processes and order counteract harmful effects of these antioxidants, has a complex system natural enzymatic non-enzymatic antioxidant defenses or mechanisms. These mainly responsible for generation different types diseases disorders. Hence protection against radical is important which can also be done by taking diet with maxim...

In this work phytochemical, pharmacological and toxicological studies were carried out on Eruca saliva,Petroselinum crispum and Anethum graveolens alcoholic extract. LDso of these extracts can not be detected, when given orally in mice. These alcoholic extracts inhibit rabbit's intestinal motility . Eruca sativa extract stimulates the uterine motility of all stages of sex cycle, while Petroseli...

The enzymatic conversion of xanthoxin to abscisic acid by cellfree extracts of Phaseolus vulgaris L. leaves has been found to be a two-step reaction catalyzed by two different enzymes. Xanthoxin was first converted to abscisic aldehyde followed by conversion of the latter to abscisic acid. The enzyme activity catalyzing the synthesis of abscisic aldehyde from xanthoxin (xanthoxin oxidase) was p...

Aiming to understand the importance of debarking on controlled utilization phenolic-rich willow biomass, biobutanol was produced from it by using Clostridium acetobutylicum. Acid-catalysed steam explosion and enzymatic hydrolysis (EH) were investigated before acetone-butanol-ethanol (ABE) fermentation. The hydrolysable sugar yield ABE fermentation efficiency found decline progressively wood (WW...

This enzyme has assumed considerable importance in studies of enzymatic acetylations since the coupling of Reaction 1 with specific CoA-linked acetyl acceptor enzyme systems (1, 3, 8-10) permits the use of acetyl phosphate as a source of acetyl groups. In the present paper a partial purification of transacetylase from extracts of Clostridium kluyveri is described and some properties of the enzy...
