Detection and Assay of Vitamin B-2 (Riboflavin) in Alkaline Borate Buffer with UV/Visible Spectrophotometry
The detection and assay of vitamin B-2 (riboflavin) was accomplished under aqueous conditions using sodium borate buffering at pH 7.52 conditions. The absorbance spectrum of riboflavin was determined at different pH values utilizing several buffers. The buffer at pH at 7.52 is followed by accurate and sensitive assay of riboflavin by spectrophotometer at 440 nm wavelength. Where indicated an or...
متن کاملParenchymatous Keratitis Following Riboflavin (Vitamin B2) Deficiency
Riboflavin or vitamin B2 (no. 1), a definite member of the 1 vitamin B complexis a pigment of the flavin type and has the empirical formula C17H20N4O?. It has also been called vitamin G, lactoflavin and ovaflavin. The other vitamin B2 (no. 2)?the P-P factor, nicotinic acid?has the formula C0H4N COOH, and its amide, C6H4N CONH?. Riboflavin has been isolated in pure form from liver, yeast and mil...
متن کاملVitamin B2 (riboflavin) and a mixture of vitamin B2 and C affects MMC efficiency in aerated media under irradiation.
Vitamin B2 (Riboflavin) acts as a strong radiation protecting agent in Escherichia coli bacteria (AB1157) in aerated media. This ability is reinforced by the addition of vitamin C. Under the influence of gamma-radiation, vitamin B2 completely suppresses the cytostatic activity of mitomycin C (MMC). In the presence of both vitamins, B2 and C, MMC is converted from an efficient cytostatic to a ra...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Detection and Quantitative Analysis for 2-Thiobarbituric Acid Utilizing Uv-Visible Spectrophotometer
The thiobarbiturates differ from other barbiturates in having a sulfur atom in place of the carbonyl oxygen at the C-2 position. The drug 2-thiobarbituric acid was found to be sufficiently soluble in 95% ethanol and 5% water for highly sensitive detection and assay. Analytical samples, including standards, were studied at 320 nanometer wavelength with background absorbance of the solvent correc...
