to evaluatethe effects of supplementing diets of growing japanese quails (n=450; 7 days old) with chromium (cr) yeast and / or mannan oligosaccharides (mos) on productive performance, carcass traits and the immune system are reported. diets were a basal diet (control) or the basal diet supplemented with 600 mg cr-yeast/kg (cr 1), 1200 mg cr-yeast/kg (cr 2), 1.0 g mos/kg, cr 1 + mos or cr 2 + mo...
Abstract Banana production generates significant amounts of agricultural wastes, being fiber extraction one the most relevant alternatives for their valorization. This process produces banana’s pseudostem pulp (BPP) as a byproduct, which shows an interesting composition biorefinery’s biochemical platform, with high polysaccharides (68%) and low lignin contents. work deals enzymatic hydrolysis (...
The taste and mouthfeel of a wine are two the most important aspects tasting. However, while much is known about phenolic compounds other macromolecules direct effects on mouthfeel, little such as oligosaccharides. This experiment uses Fructo-oligosaccharide (FOS) Galacto-oligosaccharide (GOS) at different concentrations, 450 mg/L 900 within simple model matrix. A matrix was used to control for...
The fine structure of acharan sulfate, a recently discovered glycosaminoglycan isolated from Achatina fulica , was examined. This glycosaminoglycan has a major disaccharide repeating unit of -->4)-alpha-D-GlcNpAc(1-->4)-alpha-L-IdoAp2S(1--> (where GlcNpAc is N -acetylglucosamine, IdoAp is iduronic acid, and S is sulfate) making it structurally related to both heparin and heparan sulfate. Using ...
A new, powerful method is presented for screening the binding in real time and taking place under dynamic conditions of oligosaccharides to lectins. The approach combines an SPR biosensor and HPLC profiling with fluorescence detection, and is applicable to complex mixtures of oligosaccharides in terms of ligand-fishing. Labeling the oligosaccharides with 2-aminobenzamide ensures a detection lev...
Yersinia pestis is a Gram-negative bacterium that causes plague. After Y. pestis overcomes the skin barrier, it encounters antigen-presenting cells (APCs), such as Langerhans and dendritic cells. They transport the bacteria from the skin to the lymph nodes. However, the molecular mechanisms involved in bacterial transmission are unclear. Langerhans cells (LCs) express Langerin (CD207), a calciu...
The intracellular transport of newly synthesized lysosomal hydrolases to lysosomes requires the presence of one or more phosphorylated high mannose-type oligosaccharides per enzyme. A receptor that mediates mannose-6-PO4-specific uptake of lysosomal enzymes is expressed on the surface of fibroblasts and presumably accounts for the intracellular transport of newly synthesized enzymes to the lyso...
The effect of galactoglucomannan oligosaccharides (GGMOs) compared with chemically modified oligosaccharides, GGMOs-g (with reduced number of D-galactose side chains) and GGMOs-r (with reduced reducing ends) on mung bean (Vigna radiata (L.) Wilczek) adventitious roots formation, elongation, and anatomical structure have been studied. All types of oligosaccharides influenced adventitious root fo...
Protein glycosylation involves the addition of monosaccharides in a stepwise process requiring no glycan template. Therefore, identifying the numerous glycoforms, including isomers, can help elucidate the biological function(s) of particular glycans. A method to assess the diversity of the N-linked oligosaccharides released from human serum without derivatization has been developed using on-lin...
Lipid-linked oligosaccharides were synthesized with the particulate enzyme preparation from mung bean (Phaseolus aureus) seedlings in the presence of GDP-[(14)C] mannose. The oligosaccharides were released from the lipids by mild acid hydrolysis and purified by several passages on Biogel P-4 columns. Five different oligosaccharides were purified in this way. Based on their relative elution cons...
