Phys Chem Chem Phys. 2016 Jul 20;18(29):19722-30. doi: 10.1039/c6cp03495k.

Herein, solubility experimental data for six monosaccharides, viz.d-(+)-glucose, d-(+)-mannose, d-(-)-fructose, d-(+)-galactose, d-(+)-xylose and l-(+)-arabinose, in four ionic liquids (ILs), at temperatures ranging from 288.2 to 348.2 K, were obtained aimed at gathering a better understanding of their solvation ability...

PMID: 24803696
J Food Sci Technol. 2014 May;51(5):900-7. doi: 10.1007/s13197-011-0580-0. Epub 2011 Nov 24.

Tropical roots and tubers generally contain mucilage. These mucilages exhibit unique rheological properties with considerable potential as a food thickener and stabilizer. A one-step extraction procedure was used to isolate starch free mucilage and associated proteins from a number...

J Food Sci Technol. 2014 Dec;51(12):3559-67. doi: 10.1007/s13197-012-0906-6. Epub 2012 Dec 11.

The yellow (YP) and white (WP) sections of giant swamp taro (GST) contain 40.0 g/kg and 51.5 g/kg (dry wt) respectively of pure mucilage made up of D-glucose (44.95-78.85 %), D-galactose (8.70-25.35 %), D-mannose (3.20-10.45 %), D-arabinose (2.45-5.20 %)...

Acidophilic algae isolated from mine-impacted environments and their roles in sustaining heterotrophic acidophiles.

Frontiers in microbiology

Nancucheo I, Barrie Johnson D.
PMID: 22973267
Front Microbiol. 2012 Sep 11;3:325. doi: 10.3389/fmicb.2012.00325. eCollection 2012.

Two acidophilic algae, identified as strains of Chlorella protothecoides var. acidicola and Euglena mutabilis, were isolated in pure culture from abandoned copper mines in Spain and Wales and grown in pH- and temperature-controlled bioreactors. The Chlorella isolate grew optimally...

Sugar-integrated gelators of organic solvents.

Chemistry (Weinheim an der Bergstrasse, Germany)

Gronwald O, Shinkai S.
PMID: 11695665
Chemistry. 2001 Oct 15;7(20):4328-34. doi: 10.1002/1521-3765(20011015)7:20<4328::aid-chem4328>3.0.co;2-s.

Some methyl 4,6-O-benzylidene monosaccharides can act as strong low molecular weight gelators for various organic solvents. As they are accessible in a variety of homologues, each with a unique molecular architecture, they can be used for systematic studies of...

Development and functions of seed transfer cells.

Plant science : an international journal of experimental plant biology

Thompson RD, Hueros G, Becker H, Maitz M.
PMID: 11297774
Plant Sci. 2001 Apr;160(5):775-783. doi: 10.1016/s0168-9452(01)00345-4.

In secretion or absorption processes, solutes are transported across the plasmalemma between the symplastic and apoplastic compartments. For this purpose, certain plant cells have developed a specialised transfer cell morphology characterised by wall ingrowths, which amplify the associated plasmalemma...

Cardenolides from Ornithogalum boucheanum.

Planta medica

Ghannamy U, Kopp B, Robien W, Kubelka W.
PMID: 17268991
Planta Med. 1987 Apr;53(2):172-8. doi: 10.1055/s-2006-962666.

From leaves and bulbs of ORNITHOGALUM BOUCHEANUM (Kunth) Aschers. et Graebn. (Liliaceae), cardenolides were isolated by a combination of column and droplet counter-current chromatography. Their structure elucidation was performed mainly by means of (1)H-NMR, (13)C-NMR, EI-MS, and LD-MS studies...

Content and vacuole/extravacuole distribution of neutral sugars, free amino acids, and anthocyanin in protoplasts.

Plant physiology

Wagner GJ.
PMID: 16660921

Neutral sugar, free amino acid, and anthocyanin levels and vacuole/extravacuole distribution were determined for Hippeastrum and Tulipa petal and Tulipa leaf protoplasts. Glucose and fructose, the predominant neutral monosaccharides observed, were primarily vacuolar in location. Glutamine, the predominant free...
