The biosynthesis of erythroascorbate in Saccharomyces cerevisiae and its role as an antioxidant.

Free Radic. Biol. Med. 28(2) , 183-92, (2000)

This study investigated the ability of the yeast Saccharomyces cerevisiae to synthesize ascorbate and its 5-carbon analogue erythroascorbate from a variety of precursors, and their importance as antio...

De novo asymmetric syntheses of C-4-substituted sugars via an iterative dihydroxylation strategy.

Carbohydr. Res. 341(10) , 1505-21, (2006)

A short and highly efficient route to various C-4 substituted sugar lactones has been developed. The key to the overall transformation is the sequential osmium-catalyzed dihydroxylation reaction of su...

Cellular ascorbic acid regulates the activity of major peroxidases in the apical poles of germinating white spruce (Picea glauca) somatic embryos.

Plant Physiol. Biochem. 45(3-4) , 188-98, (2007)

In previous studies we have reported that applications of ascorbic acid (ACS) enhance the conversion frequency of white spruce somatic embryos by "rescuing" structurally disorganized meristems and ind...
