Critical approaches in the catalytic transformation of sugar isomerization and epimerization after Fischer－History, challenges, and prospects

Green Energy & Environment
The transformation of aldose to ketose or common sugars into rare saccharides, including rare ketoses and aldoses, is of great value and interest to the food industry and for saccharidic biomass utilization, medicine, and the synthesis of drugs. Nowadays,

Unraveling aspects of Bacillus amyloliquefaciens mediated enhanced production of rice under biotic stress of Rhizoctonia solani

Frontiers in Plant Science, 2016
Rhizoctonia solani (RS) is a necrotrophic fungi causing sheath blight in rice leading to substantial loss in yield. Excessive and persistent use of preventive chemicals raises human health and environment safety concerns.

Synthesis of rare sugars via epimerization catalyzed by tin-organic frameworks

Current Research in Green and Sustainable Chemistry
Epimerization of readily available monosaccharides presents an atom-efficient approach to expand the portfolio of rare monosaccharides. Here, we report tin-organic frameworks (Sn-OF) as a highly selective catalyst for synthesis of rare monosaccharides ...

Morphoanatomy and biochemistry of seeds of Dicypellium caryophyllaceum (Lauraceae) at different stages of fruit maturation [PDF]

Rodriguésia
The “pau-cravo” (Dicypellium caryophyllaceum) is a tree species of the family Lauraceae, native to the Amazon rainforest. As a result of overexploitation during the last few centuries, D. caryophyllaceum has become extremely rare in Brazil.

Long-term d-allose administration ameliorates age-related cognitive impairment and loss of bone strength in male mice

Experimental Gerontology
Age-related physical and cognitive decline may be ameliorated by consuming functional foods. d-Allose, reported to have multiple health benefits, may temper aging phenotypes, particularly brain function.

Carbene-catalyzed site-selective sulfonylation and modular edition of monosaccharides for hydroxyl group stereoinversion and swapping

Nature Communications
Monosaccharides are ubiquitous motifs in natural and synthetic molecules, yet methods for their selective structure editing remain limited due to the multiple hydroxy groups for differentiation and their structural complexity.

Possibility as Monosaccharide Laxative of Rare Sugar Alcohols

YAKUGAKU ZASSHI, 2009
Allitol, D-talitol and L-iditol are sugar alcohols that are rare in nature. Due to their previous rarity, little is known about the laxative effects of these rare sugar alcohols. Therefore, reliable data on the laxative effect that these sugar alcohols cause in experimental animals could help to evaluate the effectiveness of new monosaccharide laxative
