A quantitative study of the relationship between tryptophan and niacin in Neurospora.
Numerous studies elucidating the probable pathway of tryptophan synthesis (1,2) and of niacin synthesis (3-9) in Neurospora have been reported. That tryptophan may serve as a precursor of niacin was first suggested by the results of nutritional studies with mammals (10, 11). This relationship has been confirmed for the rat by tracer experiments (12). A tryptophan-niacin relationship has also be...
متن کاملQuinolinic acid accumulation in the conversion of 3-hydroxyanthranilic acid to niacin in Neurospora.
3-Hydroxyanthranilic acid has been shown to serve as a natural precursor of niacin in Neurospora. 12 Little. information, however, has been obtained concerning the mechanism whereby the aromatic ring of 3hydroxyanthranilic acid is converted to the pyridine ring of niacin. The present paper will deal with this latter problem. Singal, et al.,I have reported that the administration of tryptophan t...
متن کاملExtended-release niacin/laropiprant: reducing niacin-induced flushing to better realize the benefit of niacin in improving cardiovascular risk factors.
Treatment with niacin effectively improves multiple lipid parameters and cardiovascular outcomes. Widespread use of niacin, however, is limited by flushing, which is mediated primarily by prostaglandin D2 (PGD2). Laropiprant is a selective PGD2 receptor 1 (DP1) antagonist that reduces objective measures of niacin-induced flushing symptoms upon initiation of therapy and with more chronic use. Re...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولConversion of monomethyl-l-tryptophan to niacin and N1-methylnicotinamide by the rat.
Gordon and Jackson (1) found that synthetic monomethyltryptophan was capable of stimulating growth in rats subsisting on a diet deficient in tryptophan. Chin (2) isolated kynurenine and kynurenic acid from the urine of rabbits after the parenteral administration of monomethylL-tryptophan (MMT). On the other hand, recent studies have shown that the albino rat, pig, horse, cotton-rat, and man can...
