THE PREPARATION OF cl-GALACTURONIC ACID FROM LEMON PECTIC ACID.*
A noteworthy advance in the knowledge of the constitution of the pectic compounds was afforded through the excellent researches of Ehrlich and his coworkers (1)) who discovered that d-galacturonic acid, an isomer of d-glucuronic acid, was a constituent of all pectic substances so far examined. Later researches showed that the pectic acid obtainable from sugar beet pectin (2) can be regarded as ...

متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولSimulation of Force Spectroscopy Experiments on Galacturonic Acid Oligomers
Pectins, forming a matrix for cellulose and hemicellulose, determine the mechanics of plant cell walls. They undergo salient structural changes during their development. In the presence of divalent cations, usually calcium, pectins can form gel-like structures. Because of their importance they have been the subject of many force spectroscopy experiments, which have examined the conformational c...
متن کاملUptake of galacturonic acid in Erwinia chrysanthemi EC16.
Uptake of [14C]galacturonic acid in Erwinia chrysanthemi was found to be stimulated during growth on pectin and its degradation products, saturated digalacturonic acid and galacturonic acid. Cells isolated from macerated potato tissue also showed increased levels of uptake activity for this molecule compared with those showed by glycerol-grown cells. Uptake was found to be an active process, an...
