Unusual protein-like, partially reversible associative behaviour has recently been observed in solutions of the water soluble carbohydrates known as 6-deoxy-6-(ω-aminoalkyl)aminocelluloses, which produce controllable self-assembling films for enzyme immobilisation and other biotechnological applications. Now, for the first time, we have found a fully reversible self-association (tetramerisation...

The use of multivalent carbohydrate compounds to block cell-surface lectin receptors is a promising strategy to inhibit the entry of pathogens into cells and could lead to the discovery of novel antiviral agents. One of the main problems with this approach, however, is that it is difficult to make compounds of an adequate size and multivalency to mimic natural systems such as viruses. Hexakis a...

In continuation of our work on glycoconjugated phthalocyanines, two new water soluble, non-ionic zinc(II) phthalocyanines have been prepared and fully characterized by means of ¹H-NMR, 13C-NMR, MALDI-TOF, ESI-TOF, UV-Vis spectroscopy, emission spectroscopy and fluorescence lifetime measurements. The carbohydrate-containing phthalonitrile precursors were synthesized through a copper-catalyzed az...

The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total ...

this research was carried out to determine the chilling and heat requirements of grapevine cultivars(rotabi, siah shiraz and yaguti) and carbohydrate and hormones changes in chilled cuttings. uniform cuttings of above mentioned cultivars were harvested when leaves were abscised in autumn, and then transferred to refrigerator (2˚c). cuttingswere subjected to 0 (unchilled control), 100, 200, 300,...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

Rapeseed meal (RSM) was subjected to different physical or chemical pretreatments to decrease residual, hard to degrade carbohydrates and to improve fermentability of RSM polysaccharides. Next, these pretreated samples were in vitro digested and fermented, with or without the addition of commercial pectinolytic enzymes. Remaining carbohydrates were quantified, and two physical characteristics w...

The carbohydrate derived nonionic gemini surfactants have been emerged as a result of our present day interest in environmentally compatible chemicals. Reverse micelles formed by surfactants can be used for selective solubilization and reactions which exploit their nanometer size, micro-environments and mimics the membranous biological system. Novel carbohydrate based non-ionic gemini surfactan...
