Conversion of glucose-1-C14 to pectin in the boysenberry.
Many authorities believe that pectins play a dominant r&e in the changes in texture of fruits during the ripening process, although the origin and fate of pectic substances in plant tissues are unknown ((1) p. 273). There is no evidence that in nature pectic substances are formed directly from galactose or galactan ((1) p. 277). To obtain some insight into the mechanism of pectin formation, glu...
متن کاملThe incorporation of formate-C14, glycine-2-C14, adenine-4, 6-C14, and phosphate-P32 into nucleic acids.
nine labeled either with C'4 or N'5. Considerable controversy has developed as to which one of these tracer compounds gives an accurate measurement of the “relativeturnover-rate― of the nucleic acids. In order to determine the “absolute turnover rate― of the nucleic acids, it is necessary to know the specific activity of the immediate precursor of the nucleic acids. Since even the ident...

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 اولThe incorporation of glycine-1-C14 by typhus rickettsiae.
A previous study has shown that under suitable conditions typhus rickettsiae can incorporate small but significant quantities of labeled methionine. For maximal uptake, adenosine 5’-triphosphate, glutamine, all of the naturally occurring amino acids, the mononucleotides, diphosphopyridine nucleotide, glutathione, and a soluble protein fraction from normal yolk sac tissues were required (1). In ...
متن کاملThe influence of vitamin E deficiency on the metabolism of sodium formate-C14 and glycine-1-C14 by the rabbit.
Several recent, reports from this laboratory have implicated vitamin E in the metabolism of the nucleic acids. It was shown that vitamin E-deficient rabbits excrete extra quantities of allantoin (1) and that the livers from such animals exhibit greatly increased xanthine oxidase activities (2). Finally it haa been shown that vitamin E deprivation in the rat, leads to an increased incorporation ...
