A common need for microbial cells is the ability to respond to potentially toxic environmental
insults. Here we review the progress in understanding the response of the yeast …

Humans are unable to synthesise l‐ascorbic acid (L‐AA, ascorbate, vitamin C), and are thus
entirely dependent upon dietary sources to meet needs. In both plant and animal …

Hydrogen peroxide (H2O2) sensing and signaling involves the reversible oxidation of
particular thiols on particular proteins to modulate protein function in a dynamic manner …

Ever since Linus Pauling published his studies, the effects of vitamin C have been
surrounded by contradictory results. This may be because its effects depend on a number of …

Vitamin C (ascorbic acid (AA)) is very popular for its antioxidant properties. Consequently,
many other important aspects of this multifaceted molecule are often underestimated or even …

The production of fruit vinegars as a way of making use of fruit by-products is an option
widely used by the food industry, since surplus or second quality fruit can be used without …

▪ Abstract The structure of the familiar antioxidant l-ascorbic acid (vitamin C) was described
in 1933 yet remarkably, its biosynthesis in plants remained elusive until only recently. It …

The essential process of iron-sulfur (Fe/S) cluster assembly (ISC) in mitochondria occurs in
three major phases. First,[2Fe-2S] clusters are synthesized on the scaffold protein ISCU2; …

Abstract l-ascorbic acid (vitamin C) was first isolated in 1928 and subsequently identified as
the long-sought antiscorbutic factor. Industrially produced l-ascorbic acid is widely used in …

Biosynthesis of l-ascorbate (vitamin C) occurs by different pathways in plants and mammals.
Yeast contain d-erythroascorbate, a C 5 analog of ascorbate. UDP-d-glucuronic acid is the …
