L-Ascorbic Acid Peroxidase
Euglena gracilis was found to contain a peroxidase that specifically requires L-ascorbic acid as the natural electron donor in the cytosol. The presence of an oxidation-reduction system metabolizing L-ascorbic acid was demonstrated in Euglena cells. Oxidation of L-ascorbic acid by the peroxidase, and the absence of ascorbic acid oxidase activity, suggests that the system functions to remove H20...
متن کاملL-Ascorbic acid degradation by bacteria. VIII. All the pathway in the L-ascorbic acid metabolism.
The medium used contained 3g of substrate, 150ml of 1/15M phosphate buffer and 150ml of sterile distilled water. 0.5g (dry weight) of the adapted cells was added to the medium and the whole was incubated at 30•‹ for 20 hours. For detecting the intermediate products, paper chromatography was chiefly used. For developing the nonvolatile acids, n-butanol-acetic acid-water (4:1:1) was used and the ...
متن کاملBiological synthesis of L-ascorbic acid in animal tissues: conversion of L-gulonolactone into L-ascorbic acid.
The enzyme system catalysing the conversion of D-glucuronolactone and L-gulonolactone into Lascorbic acid in animal tissues has been previously reported to be entirely located in the microsomal fractions ofratand goat-liver homogenates (Burns, Peyser & Moltz, 1956; Chatterjee, Ghosh, Ghosh & Guha, 1957a, b; 1958a, b). The kidney tissue has been found to be the site of this conversion in amphibi...

متن کاملl-Ascorbic Acid Biosynthesis in Ochromonas danica.
Ochromonas danica Pringsheim, a freshwater chrysomonad, converts d-glucose into l-ascorbic acid over a metabolic pathway that ;inverts' the carbon chain of the sugar. In this respect, l-ascorbic acid formation resembles that found in ascorbic acid-synthesizing animals. It differs from this process in that d-galacturonate and l-galactono-1,4-lactone, rather than d-glucuronate and l-gulono-1,4-la...
