Synthesis of C14-Labeled L-Sorbose and L-Ascorbic Acid
A m ethod is prese nted for preparing C'4-l abeled L-ascorbi c acid (vi tamin C) from labeled banum D-gluconate or D-glucose. The process is adapted from t he commercial synthesis of vi tamin C t hrough sorbitol, L-sorbose and potassium di-O-isopropylidene-2kelo-L-guloll.ate. In .th e cyanohydrin . synt hesis of labeled D-glucose, barium D-gluconate is used as an lI1term ed~at~ . Fo: prepanng l...

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 کاملAscorbic acid synthesis in normal and drug-treated rats, studied with L-ascorbic-1-C14 acid.
It is known that, of all animal species studied, only man, other Primates, and the guinea pig are unable to synthesize ascorbic acid. Results obtained in rats, with radioactive glucose, indicate that ascorbic acid is synthesized by a fairly direct route from glucose (l-3), but no information has been available concerning the rate of synthesis and metabolism of ascorbic acid. Such information wo...
متن کاملSynthesis of new L-ascorbic ferulic acid hybrids.
A feasibility and chemical study of the coupling conditions of L-ascorbic acid with ferulic acid derivatives are described on the basis of the known synergistic effects of mixtures of various antioxidants. Novel L-ascorbic ferulic hybrids linked at the C-3 hydroxyl group were prepared with the aim to protect the alcohol function and the enediol system.
