But, of course, glucosides are glycosides.. Glycosides are constituents bound to a sugar, and in a glucoside the sugar is glucose. In a fructoside the sugar is fructose, in a galactoside the sugar is galactose (dunno how youd get milk sugar into a plant, though), and so on.. Because of that sugar glycosides usually start working in the gut, after the sugar has been stripped away.. Glycosides are water- and alcohol-soluble.. The cyanoglycosides are found in most if not all rose family plants. You get cyanide from cyanoglycosides; theyll stop you breathing if you ingest large enough amounts of them.. Youll find heart glycosides in foxglove (Digitalis spp.) and a lot of other plants which act on the heart. The glycosides digitoxin, digitalein, digitonin, digitalin and so on are cumulative and toxic; they work in doses rather too close to the deadly dose, and they will kill people who regularly take them -- if these folks suddenly get much weaker. The thing is, though, that without these toxic ...
TY - JOUR. T1 - Two different modes of inhibition of the rat brain Na+, K+-ATPase by triterpene glycosides, psolusosides A and B from the holothurian Psolus fabricii. AU - Gorshkova, Irina A.. AU - Kalinin, Vladimir I.. AU - Gorshkov, Boris A.. AU - Stonik, Valentin A.. PY - 1999/1/1. Y1 - 1999/1/1. N2 - Effects of two triterpene glycosides, isolated from the holothurian Psolus fabricii, on rat brain Na+, K+-ATPase (Na, K-pump; EC 3.6.1.3) were investigated. Psolusosides A and B (PsA and PsB) inhibited rat brain Na+, K+-ATPase with I50 values of 1 x 10-4 M and 3 x 10-4 M, respectively. PsA significantly stimulated [3H]ATP binding to Na+, K+-ATPase, weakly increased [3H]ouabain binding to the enzyme, and inhibited K+-phosphatase activity to a smaller degree than the total reaction of ATP hydrolysis. In contrast, PsB decreased [3H]ATP binding to Na+, K+-ATPase, and had no effect on [3H]ouabain binding to the enzyme. K+-Phosphatase activity was inhibited by PsB in parallel with Na+, K+-ATPase ...

In molecular biology, glycoside hydrolase family 79 is a family of glycoside hydrolases. Glycoside hydrolases EC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families. This classification is available on the CAZy(http://www.cazy.org/GH1.html) web site, and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes. Glycoside hydrolase family 79 includes endo-beta-N-glucuronidase EC 3.2.1.31 and heparanase (CAZY GH_79). Heparan sulphate proteoglycans (HSPGs) play a key role in the self- assembly, insolubility and barrier properties of basement membranes and extracellular matrices. Hence, cleavage of heparan sulphate (HS) affects the integrity and functional state of tissues and thereby fundamental normal and pathological phenomena ...

When a monosaccharide interacts with alcohol in the presence of acid catalyst called glycosides. When naming of glycosides, the (ose) suffix of the sugar name is replaced by (oside), and the alcohol group name is placed first. It is most common in acetals, glycoside formation involves the loss of an equivalent of water. The diether product is stable to base and alkaline oxidants such as Tollens reagent. Since acid-catalyzed aldolization is reversible, glycosides may be hydrolyzed back to their alcohol and sugar components by aqueous acid. ...

The methyl glycosides of N-acetyl-d-glucosamine (d-GlcNAc) and N-acetyl-d-galactosamine (d-GalNAc) have been used as model glycan analogs to study the effects of lithium cation binding on glycan structure in gas-phase experiments. Infrared multiple photon dissociation (IRMPD) spectra for the two Li+-complexed anomers of methyl-d-GlcNAc revealed a difference of 10 cm−1 between their respective carbonyl stretching band positions. A corresponding 11 cm−1 shift was observed for the two Li+-complexed anomers of methyl-d-GalNAc. Theoretical calculations indicate that the position of the methyl group (α and β, or axial and equatorial, respectively) on carbon 1 of the sugar and its close proximity to the carbonyl of the acetamido group on carbon 2 cause the average orientation of the carbonyl to change in order to minimize steric hindrance. This change in orientation is postulated to be the cause of the observed Cdouble bond; length as m-dashO stretching band shift. The calculations also predict ...

Saccharide is also called carbohydrate, consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with the empirical formula Cm(H2O)n. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Carbohydrates perform numerous roles in living organisms. Polysaccharides serve for the storage of energy (e.g. starch and glycogen) and as structural components. The 5-carbon monosaccharide ribose is an important component of coenzymes (e.g. ATP, FAD and NAD) and the backbone of the genetic molecule known as RNA. The related deoxyribose is a component of DNA. Saccharides and their derivatives include many other important biomolecules that play key roles in the immune system, fertilization, preventing pathogenesis, blood clotting, and development.. A glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store ...

RATIONALENegative ESI-QIT-MS of several subtypes of flavonoid O-glycosides is known to produce deprotonated molecular ions which undergo homolytic fragmentation at the glycosidic bond upon collision-induced dissociation (CID). However, these subtypes have never been simultaneously compared under unified MS conditions.. METHODSThe (-)-ESI-MSn fragmentations of 69 flavonoid O-glycosides, involving eight subtypes, were analyzed using a quadrupole ion-trap mass spectrometer with collision energies varying from 18-44%. Factors influencing the homolytic glycosidic bond fragmentation, such as collision energy, hydroxylation of aglycone, and glycosylation pattern, were comprehensively studied.. RESULTSUnder the unified CID-QIT-MS2 conditions, the precursor deprotonated molecular ions [M-H](-) for 3-O-glycosyl, 3,7-di-O-glycosyl and 3,6,7-tri-O-glycosyl flavonols experienced homolytic fragmentation at the glycosidic bond and generated the radical aglycone ion [Y-0-H](-center dot). This gas-phase CID ...
Examination of the bulbs of Lilium pumilum (Liliaceae) led to the isolation of four novel steroidal glycosides (1-4) with a 2,3,4-trisubstituted β-d-glucopyranosyl unit. In 1 and 3, the α-L-arabinopyranosyl moiety is linked to C-3 of the inner trisubstituted β-D-glucopyranosyl group and is present as an usual 4C1 conformation. In contrast, in 2 and 4, the α-L-arabinopyranosyl moiety, which is attached to C-4 of the inner trisubstituted β-D-glucopyranosyl group, is present as a 1C4 conformation. The structures of the new steroidal glycosides were determined based on the results of spectroscopic analyses, including two-dimensional (2D) NMR data and hydrolysis.

Abstract: Premise of the study: Microsatellite primers were developed for the common milkweed, Asclepias syriaca, to assist in genet identification and the analysis of spatial genetic structure. • Methods and Results: Using an enrichment cloning protocol, eight microsatellite loci were isolated and characterized in a North American population of A. syriaca. The primers amplified di- and tri-nucleotide repeats with 4-13 alleles per locus. • Conclusions: The primers will be useful for studies of clonality and gene flow in natural populations. Abstract: Chapter 3 Spatial genetic structure (SGS) is largely determined by the reproductive strategies of species. Many plant species, including Asclepias syriaca, the common milkweed, reproduce both sexually and asexually and there can be great variation in SGS among species that reproduce by both methods. SGS was assessed within an old field population of A. syriaca in northern Michigan. Strong SGS was detected to 38 m when multiple identical ...

Glycosides are compounds which contain two parts: a sugar component which is in its cyclic (ring) form, and another component attached to the sugar at the number 1 (or "glycosidic" carbon). Some of these companion molecules can also be sugars, so sucrose, being a 2-sugar molecule (disaccharide) made of one glucose unit and one fructose unit attached through the appropriate carbon, is an example of one of these types of glycosides. The glycosides which appear to influence beer flavor are found in hops and have aromatic compounds bonded to the carbohydrates. In their combined state, the glycosides have no flavor; no sweetness and no aroma. However, once this glycosidic bond is broken the aromatic compound is free to volatilize into the headspace of the beer and ultimately into your nose ...

As a rule, about 1% of genes in a given genome encode glycoside hydrolases and their homologues. On the basis of sequence similarity they have been grouped into more than ninety GH families during the last 15 years. The GH97 family has been established very recently and initially included only 18 bacterial proteins. However, the evolutionary relationship of the genes encoding proteins of this family remains unclear, as well as their distribution among main groups of the living organisms. The extensive search of the current databases allowed us to double the number of GH97 family proteins. Five subfamilies were distinguished on the basis of pairwise sequence comparison and phylogenetic analysis. Iterative sequence analysis revealed the relationship of the GH97 family with the GH27, GH31, and GH36 families of glycosidases, which belong to the α-galactosidase superfamily, as well as a more distant relationship with some other glycosidase families (GH13 and GH20). The results of this study show an

The later is unusual in GHs, and a divergence from GH29, but is likely necessary to avoid electronic repulsion with the substrate sulfate groups. These two residues have been identified by structural superimposition with GH29 enzymes, and are conserved within the few members of the GH107 family. The catalytic His has been further confirmed by the lack of activity of the H294Q mutant of Mariniflexile fucanivorans [2]. The catalytic aspartate was also proposed to be one of the catalytic residue on sequence analysis alone, in a simultaneously released paper [3]. ...

Trypsin inhibitors. Trypsin inhibitors are a type of anti-nutritional factors that can inhibit the activities of some digestive enzymes in human intestines and hinder our dietary intake of nutrients. Soya beans contain trypsin inhibitors. Nonetheless, trypsin inhibitors can be destroyed by soaking the soya beans well and cooking them thoroughly in boiling water.. Cyanogenic glycosides. Cyanogenic glycosides occur naturally in over 2 000 plant species, quite a number of which are food plants. Different types of cyanogenic glycosides may be found in different cyanogenic food plants, for example, taxiphyllin in bamboo shoots, and linamarin in cassava. Cyanogenic glycosides per se are relatively non-toxic. However, upon human consumption of cyanogenic plants, non-toxic cyanogenic glycosides will be decomposed into toxic hydrogen cyanides by hydrolysis in the intestinal tracts. The potential toxicity of a cyanogenic plant depends primarily on its capacity to produce hydrogen cyanides. Cyanide ...
Toxicological testing showed that the substances are not genotoxic, nor carcinogenic, or linked to any adverse effects on the reproductive human system or for the developing child. The Panel set an Acceptable Daily Intake (ADI)[1] of 4 mg per kg body weight per day for steviol glycosides, a level consistent with that already established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA).. The Panel points out, however, that this ADI could be exceeded by both adults and children if these sweeteners are used at the maximum levels proposed by the applicants.. Steviol glycosides are intense sweeteners extracted from the leaves of the stevia plant (Stevia rebaudiana Bertoni). These substances, such as stevioside and rebaudioside, range in sweetness from 40 to 300 times sweeter than sucrose.. EFSA reviewed the safety of three dossiers supporting requests for authorisation. Food additives such as sweeteners must be explicitly authorised at European level before they can be used in ...

article{9b276fde-3141-41ff-ba06-611da1a392ac, abstract = {,p,Lipases and glycoside hydrolases have large similarities concerning reaction mechanisms. Acyl-enzyme intermediates are formed during lipase-catalyzed reactions and in an analogous way, retaining glycoside hydrolases form glycosyl-enzyme intermediates during catalysis. In both cases, the covalent enzyme intermediates can react with water or other nucleophiles containing hydroxyl groups. Simple alcohols are accepted as nucleophiles by both types of enzymes. Lipases are used very successfully in synthesis applications due to their efficiency in catalyzing reversed hydrolysis and transesterification reactions. On the other hand, synthesis applications of glycoside hydrolases are much less developed. Here, important similarities and differences between the enzyme groups are reviewed and approaches to reach high synthesis yields are discussed. Useful strategies include the use of low-water media, high nucleophile concentrations, as well as ...
The transformation of cellulose into long-chain alkyl glycoside surfactants has been carried out following two different routes: (1) Direct transformation of cellulose to butyl-, hexyl-, octyl-, decyl- and dodecyl-a,ß-glycosides in an ionic liquid media and Amberlyst-15Dry as catalysts, with mass yield of up to 82%; and (2)two steps reaction with transformation of cellulose into methyl glucosides, with a procedure described by Zhang et al., followed by transacetalation with 1-octanol and 1-decanol in the presence of Amberlyst-15Dry. A kinetic study for the direct transformation of cellulose using 1-octanol has shown that depolymerisation of cellulose continues during the Fischer glycosidation. Increasing the chain length of the alcohol decreases the global reaction rate owing to an increase in the lipophilicity of the alcohol that decreases its contact with the carbohydrates. Finally, several acid catalysts were tested and the best results were obtained with Amberlyst-15Dry ...

The regulation impact assessment concluded that the benefits of permitting use of steviol glycosides outweigh any costs associated with its use."​. Stevia ins-and-outs​. Steviol glycosides - the extract of the leaves of the plant Stevia rebaudiana​ - are a group of intense sweeteners. "Stevia is not a new invention and thus no company holds a patent and would go to the expense of approval just to let other companies cash in on their approval,"​ said Prof. Midmore. The sweetener is being lined up initially for beverages. Indeed, two giants of the sector - Pepsi and Coca-Cola - are both active in bringing their own stevia brands to the market based on rebiana, the sweetest, purest part of the stevia leaf, and reportedly about 200 times as sweet as sugar.​. The approval from Australia and New Zealand means that such companies "could, I believe, use the current approval to enter into the Australian market," ​said Prof. Midmore. "But this is provided that they are not enzymatically ...

2,3-Di-O-benzyl-4,6-O-benzylidene-thiohexopyranosides, on activation with 1-benzenesulfinyl piperidine and triflic anhydride, react with allyl silanes and stannanes, and with silyl enolethers to give C-glycosides. In the mannose series the beta-isomers are formed selectively whereas the glucose series provides the alpha-anomers. This selectivity pattern parallels that of O-glycoside formation and eliminates the need to consider donor-acceptor hydrogen bonding in the formation of the O-glycosides.
Vicia sativa seeds are a potential alternative protein source for pigs due to their high protein and lysine content, but their use in pig feeding has been limited by the detrimental effects of their toxins on feed intake and growth performance. Maximum safe levels of 20% for growing pigs and 10% for piglets are often cited (Enneking, 1995). It is noted that the content of cyanoalanine and cynogenic glycosides differs dramatically amongst individual cultivars and may depend on other factors (cyanogenic glycosides are reported to increase in the plant after flowering). Therefore, the safe feeding of Vicia sativa seeds depends on the cultivar used (Enneking, 1995).. In Australia, low-cyanoalanine varieties have been marketed as suitable for pigs up to 35% of the diet, though a more reasonable 10% inclusion rate was considered to be encouraging enough to lead to an increased planting of this species (Enneking, 1995). The Morava cultivar, which contains very low levels of cyanoalanine (less than 7 ...
