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 ...
15 صفحه اولOn the interaction of avidin and oleic acid.
Under appropriate conditions, oleic acid replaces biotin for several lactic acid bacteria.‘, z This growth-promoting action of oleic acid is not nullified by excess avidin for Streptococcus jaecalis R2 or for several other organisms (Table I). Egg white did, however, block utilization of oleic acid by Lactobacillus arabinosus (Table I). This result is obtained whether oleic acid is added alone,...
متن کاملWho Is Mr. HAMLET? Interaction of Human R-Lactalbumin with Monomeric Oleic Acid
A specific state of the human milk Ca2+ binding protein R-lactalbumin (hLA) complexed with oleic acid (OA) prepared using an OA-pretreated ion-exchange column (HAMLET) triggers several cell death pathways in various tumor cells. The possibility of preparing a hLA-OA complex with structural and cytotoxic properties similar to those of the HAMLET but under solution conditions has been explored. T...
متن کاملConversion of oleic acid to linoleic acid.
Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...
متن کاملPreparation and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid
The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...
