Vitamin C (l-ascorbic acid) has important antioxidant and metabolic functions in both plants
and animals, but humans, and a few other animal species, have lost the capacity to�…

Increasing the l-ascorbate (vitamin C) content of crops could in principle involve promoting
its biosynthesis or inhibiting its degradation. Recent progress has revealed biosynthetic�…

MAN, other primates and guinea pig are the only mammals that are known to be unable to
synthesize l-ascorbic acid; thus they require vitamin C in their diet to prevent scurvy. The rat�…

▪ 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�…

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�…

IT has long been known that an enzyme catalysing the reduction of dehydro-l-ascorbic acid
(DHA) by glutathione to ascorbic acid occurs in plant tissues1–3. It can also be shown that�…

The biosynthetic pathway of L-ascorbic acid (vitamin C) in plants has been established for
several years. However, recent reports describe alternative pathways, revealing a more�…

Ascorbic acid (vitamin C) is an abundant component of plants. It reaches a concentration of
over 20 m M in chloroplasts and occurs in all cell compartments, including the cell wall. It�…

The biosynthesis of L-ascorbic acid (vitamin C) is not well understood in plants. The ozone-
sensitive Arabidopsis thaliana mutant vitamin c-1 (vtc1; formerly known as soz1) is deficient�…
