Enzymatic oxidation of vitamin A aldehyde to vitamin A acid.
Studies indicating that vitamin A (1) and vitamin A aldehyde (2) are metabolized to water-soluble degradation products and CO% provide support for the suggestion (3) that there exists an oxidative pathway of major importance in the metabolism of vitamin A. The detection of vitamin A aldehyde in the liver (4, 5) and observations (6-8) that dietary vitamin A acid supports the growth of vitamin A-...
متن کاملThe colorimetric reaction between vitamin A2 aldehyde and antimony trichloride.
1. Columns of Sephadex G-25 have been used for the preliminary fractionation of tryptic digests of casein. 2. Fractions from Sephadex columns have been examined for their ability to stimulate the growth of a strain of Streptococcus equi8imili8. Maximum stimulatory activity appeared to be localized in a fairly narrow region of the total peptide material. 3. Further fractionation of peptides deri...
متن کاملP-91: Vitamin E and Selenium Supplementation Affects Aldehyde Oxidase, Xanthine Dehydrogenase/Oxidase Activities In Diabetic Rat Ovaries
Background Any factor like diabetes that changes the oxidant/antioxidant balance in favor of oxidants could possibly disrupt the physiologic function of ovaries. So, we have investigated the effect of vitamin E and Se supplements on antioxidant defense in ovaries of diabetic rats with focus on Xanthine dehydrogenase/oxidase (XDH/XO) and Aldehyde oxidase (AO) activities. MaterialsAndMethods This...
متن کاملHepatic Aldehyde Oxidase
Previous reports on rabbit liver aldehyde oxidase described the purification and some properties of the enzyme (1) and the differential inhibition of electron transfer to various acceptors (2). The latter study furnished evidence for the participation of several electron carriers in the internal electron transport sequence of the enzyme. The present communication summarizes the results of studi...
متن کاملBiomimetic flavin-catalyzed aldehyde oxidation.
The oxidation of alkyl and aryl aldehydes to their corresponding carboxylic acids has been achieved through the action of a biomimetic bridged flavin catalyst. The reaction uses readily available 35% aqueous hydrogen peroxide and is operationally simple. The oxidation is a green and sustainable reaction, obviating chlorinated solvents with minimal byproducts.
