CONDENSATION OF CERTAIN NITRILES AND VARIOUS POLY-HYDROXYPHENOLS TO FORM PHENOLIC ACIDS

The metabolism of certain acids, amides and nitriles within plant tissues.

The plant growth-regulating activities of the first six members of the homologous series (2:4-dichlorophenoxy) alkanecarboxylie acids and the corresponding amides and nitriles have been assessed in the wheat cylinder, pea curvature, pea segment and tomato-leaf epinasty tests. The breakdown of these compounds when metabolized under standard conditions in wheat coleoptile and pea-stem tissues has...

در فصل اول مقدمات و پیش نیازهای لازم برای فصل های بعدی فراهم گردیده است . در فصل دوم مساله توسیع مورد توجه قرار گرفته و ابتدا شرایطی که تحت آن از یک فشرده سازی نیم گروهی خاص یک زیرگروه نرمال بسته یک گروه به یک فشرده سازی متناظر با فشرده سازی اولیه برای گروه رسید مورد بررسی قرار گرفته و سپس ارتیاط بین ساختارهای مختلف روی این دو فشرده سازی از جمله ایده آل های مینیمال چپ و راست و... مورد بررسی قرا...

Microbial transformation of nitriles to high-value acids or amides.

Biotransformation of nitriles mediated by nitrile-amide converting enzymes has attracted considerable attention and developed tremendously in the recent years in China since it offers a valuable alternative to traditional chemical reaction which requires harsh conditions. As a result, an upsurge of these promising enzymes (including nitrile hydratase, nitrilase and amidase) has been taking plac...

Response of laying hens to supplementation with various fatty acids when fed diets inadequate in protein and sulphur amino acids

Screening of various phenolic acids and flavonoid derivatives for their anticholinesterase potential.

Alzheimer's disease (AD), the most common form of dementia, is a neurodegenerative disease characterized by progressive cognitive deterioration together with declining activities of daily living and neuropsychiatric symptoms or behavioural changes. The oldest, on which most currently available drug therapies are based, is known as the "cholinergic hypothesis" and suggests that AD begins as a de...
