The Organic Acids of Rhubarb (rheum Hybridum)*
“General pronouncements on the significance of the plant acids are at present probably of little value. . . The true significance of the acid metabolism of plants may perhaps lie close to Kostytchev’s later point of view that these acids are the building stones from which some of the complex plant products originate. . . The plant acids are possibly convertible into amino acids and proteins, co...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولThe Organic Acids of Rhubarb (rheum Hybridum) * I. on the Malic Acid of Rhubarb, with a Note on the Malic Acid of Tobacco Leaves
The extensive literature on the occurrence of malic acid in plant tissues was reviewed by Franeen and Keyssner (1) in 1923. Although they found that the conclusive tests of isolation and chemical identification had been applied in relatively few cases, there is no question that this acid is widely distributed in nature and is of great importance in plant metabolism. In those instances in which ...
متن کاملQuantitative evaluation of the pH profile in organic acid fermentations.
One of the most important considerations in designing an integrated process for the production of organic acids is the strong pH dependence of the process parameters. The release of the acidic products during the fermentation alters the pH of the broth and subsequently affects the kinetics of cell growth and product formation. In addition, some parameters (such as the distribution coefficient o...
متن کاملBiofunctional organic nanocrystals for quantitative detection of pathogen deoxyribonucleic acid.
Advances in nanotechnology have had significant impacts in the field of biodiagnostics. In this study, we describe the novel application of dissolvable, organic and biofunctional nanocrystals for the quantitative detection of a PCR product. Fluorescein diacetate (FDA), a fluorogenic precursor of fluorescein, was milled in a solution of a polymeric surfactant to create a stable, nanosized colloi...
