Studies of the biosynthesis of orotic acid.
* The data in this paper have been taken from a thesis presented by Ray Wu to the Graduate School of Arts and Sciences of the University of Pennsylvania in partial fulfilment of the requirements for the degree of Doctor of Philosophy. An abstract of a preliminary report of this work has appeared (1). Aided by a grant from the American Cancer Society, administered by the Committee on Growth of t...
متن کاملHistochemical study on orotic acid.
Recently orotic acid has been noticed as a growth factor and regarded as a pre cursor of nucleic acid (1, 2). But its distribution in organisms has scarcely been studied except for tracing the acid using C14-labeled compound (3). The authors have found that orotic acid shows a whitish blue primary fluorescence, which is re markably intensified by adding H2O2. Applying this property to histochem...
متن کاملSquare wave voltammetric determination of valproic acid in pharmaceutical Preparations
The electrochemical behavior of valproic acid (VAL) was investigated using square wave voltammetry, cyclic voltammetry, and sampled direct current polarography and a new square wave voltammetric method was developed for determination of VAL in pharmaceutical preparations. VAL showed two reduction peaks at about –0.2 V and –0.8 V vs. Ag/AgCl 3 M KCl with a hanging mercury drop electrode in 0.05 ...
متن کاملDetermination of impurities in pharmaceutical preparations containing folic acid.
In the presented study, the HPLC method was used for the determination of impurities (p-aminobenzoic acid and p-aminobenzoyl-L-glutamic acid) in single-component pharmaceutical products containing folic acid. The determination was performed using a spectrophotometric detector at lambda = 269 nm wavelength.
متن کاملOrotic acid in milk.
Other studies in this laboratory (1) drew our attention to the possibility that erotic acid might be concerned with the maintenance of adequate lactation in the rat and with the survival of the young. Since no data were available on the erotic acid content of milk, this study was undertaken. The occurrence of erotic acid as a component of milk has been indicated since 1904, when Biscaro and Bel...
