study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

The Metabolism of Acetic Acid, Propionic Acid and Butyric Acid in Sheep.

7. Comparison of specific radioactivities of blood lactate and plasma glucose during the infusion of [14C]glucose or [14C]lactate indicated that about 6% of glucose was recycled through the glucose-lactate interconversion. Evidence from the relocation of 14C in glucose during the infusion of [6-_4C]glucose indicated about 10% of recycling. 8. Negligible incorporation of glucose or lactate into ...

Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness

  Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...

Acetic acid

Acylation of hydrazides with acetic acid and formic acid.

In peptide synthesis, hydrazides are important intermediates for the azide coupling method. A hydrazide is converted to the corresponding azide in the presence of an acid and a nitrite. When acetic acid (or formic acid) is used as the acid, partial acetylation (or formylation) of the hydrazide occurs as a side reaction. Formylation of the hydrazide is much faster than acetylation. Removal of th...
