Ascorbic acid is synthesised by eukaryotes, the known exceptions being primates and some
other animal groups which have lost functional gulonolactone oxidase. Prokaryotes do not …

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 …

Vitamin C (ascorbic acid) plays important roles as an anti-oxidant and in collagen synthesis.
These important roles, and the relatively large amounts of vitamin C required daily, likely …

Protein structure and function can be altered by reactive oxygen species produced either by
cell metabolism or by external oxidants. Although catalases, superoxide dismutases and …

▪ 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 poultry industry has been searching for a replacement for antibiotic growth promoters in
poultry feed as public concerns over the use of antibiotics and the appearance of antibiotic …

Free radicals play a key role in the ageing process. However, free radicals are small,
reactive and short lived and thus challenging to measure. We utilize a new technique called …

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 …

Peroxiredoxins (Prx) are widely distributed peroxidases that can be divided into 1-Cys and 2-
Cys Prx groups based on the number of conserved cysteine residues that participate in their …

This text emphasises the importance of staying informed about Saccharomyces cerevisiae
as it provides the intellectual basis for much of the molecular and cellular biology of …
