Thermus aquaticus ATCC 33923 amylomaltase gene cloning and expression and enzyme characterization: production of cycloamylose. (1/213)

The amylomaltase gene of the thermophilic bacterium Thermus aquaticus ATCC 33923 was cloned and sequenced. The open reading frame of this gene consisted of 1,503 nucleotides and encoded a polypeptide that was 500 amino acids long and had a calculated molecular mass of 57,221 Da. The deduced amino acid sequence of the amylomaltase exhibited a high level of homology with the amino acid sequence of potato disproportionating enzyme (D-enzyme) (41%) but a low level of homology with the amino acid sequence of the Escherichia coli amylomaltase (19%). The amylomaltase gene was overexpressed in E. coli, and the enzyme was purified. This enzyme exhibited maximum activity at 75 degrees C in a 10-min reaction with maltotriose and was stable at temperatures up to 85 degrees C. When the enzyme acted on amylose, it catalyzed an intramolecular transglycosylation (cyclization) reaction which produced cyclic alpha-1,4-glucan (cycloamylose), like potato D-enzyme. The yield of cycloamylose produced from synthetic amylose with an average molecular mass of 110 kDa was 84%. However, the minimum degree of polymerization (DP) of the cycloamylose produced by T. aquaticus enzyme was 22, whereas the minimum DP of the cycloamylose produced by potato D-enzyme was 17. The T. aquaticus enzyme also catalyzed intermolecular transglycosylation of maltooligosaccharides. A detailed analysis of the activity of T. aquaticus ATCC 33923 amylomaltase with maltooligosaccharides indicated that the catalytic properties of this enzyme differ from those of E. coli amylomaltase and the plant D-enzyme.  (+info)

Granule-bound starch synthase I in isolated starch granules elongates malto-oligosaccharides processively. (2/213)

Isoforms of starch synthase belonging to the granule-bound starch synthase I (GBSSI) class synthesize the amylose component of starch in plants. Other granule-bound isoforms of starch synthase, such as starch synthase II (SSII), are unable to synthesize amylose. The kinetic properties of GBSSI and SSII that are responsible for these functional differences have been investigated using starch granules from embryos of wild-type peas and rug5 and lam mutant peas, which contain, respectively, both GBSSI and SSII, GBSSI but not SSII and SSII but not GBSSI. We show that GBSSI in isolated granules elongates malto-oligosaccharides processively, adding more than one glucose molecule for each enzyme-glucan encounter. Granule-bound SSII can elongate malto-oligosaccharides, but has a lower affinity for these than GBSSI and does not elongate processively. As a result of these properties GBSSI synthesizes longer malto-oligosaccharides than SSII. The significance of these results with respect to the roles of GBSSI and SSII in vivo is discussed.  (+info)

Stable, inducible thermoacidophilic alpha-amylase from Bacillus acidocaldarius. (3/213)

Bacillus acidocaldarius Agnano 101 produces an inducible thermoacidophilic alpha-amylase. The enzyme production occurs during the stationary phase of growth in the presence of compounds with alpha-1,4-glucosidic linkages. The enzymatic activity is both present in the culture medium and associated with the cells; the enzymes purified from both sources show identical molecular and catalytic properties. The purified amylase has a single polypeptide chain of molecular weight 68,000 and behaves like an alpha-amylase with affinity constants for starch and related substances of 0.8 to 0.9 mg/ml. The pH and temperature optima for activity are 3.5 and 75degreesC, respectively. The amylase is stable at acidic pH (below 4.5). Its thermal stability is strictly dependent upon protein concentration; the half-life at 60degreesC of the amylase in a 70-mug/ml solution is about 5 days.  (+info)

Mechanism of porcine pancreatic alpha-amylase inhibition of amylose and maltopentaose hydrolysis by kidney bean (Phaseolus vulgaris) inhibitor and comparison with that by acarbose. (4/213)

The effects of Phaseolus vulgaris inhibitor (alpha-AI) on the amylose and maltopentaose hydrolysis catalysed by porcine pancreatic alpha-amylase (PPA) were investigated. Based on a statistical analysis of the kinetic data and using the general velocity equation, which is valid at equilibrium for all types of inhibition in a single-substrate reaction, it was concluded that the inhibitory mode is of the mixed noncompetitive type involving two molecules of inhibitor. In line with this conclusion, the Lineweaver-Burk primary plots intersect in the second quadrant and the secondary plots of the slopes and the intercepts versus the inhibitor concentrations are parabolic curves, whether the substrate used was amylose or maltopentaose. A specific inhibition model of the mixed noncompetitive type applies here. This model differs from those previously proposed for acarbose [Al Kazaz, M., Desseaux, V., Marchis-Mouren, G., Payan, F., Forest, E. & Santimone, M. (1996) Eur. J. Biochem. 241, 787-796 and Al Kazaz, M., Desseaux, V., Marchis-Mouren, G., Prodanov, E. & Santimone, M. (1998) Eur. J. Biochem. 252, 100-107]. In particular, with alpha-AI, the inhibition takes place only when PPA and alpha-AI are preincubated together before the substrate is added. This shows that the inhibitory PPA-alphaAI complex is formed during the preincubation period. Secondly, other inhibitory complexes are formed, in which two molecules of inhibitor are bound to either the free enzyme or the enzyme-substrate complex. The catalytic efficiency was determined both with and without inhibitor. Using the same molar concentration of inhibitor, alpha-AI was found to be a much stronger inhibitor than acarbose. However, when the inhibitor amount is expressed on a weight basis (mg x L-1), the opposite conclusion is drawn. In addition, limited proteolysis was performed on PPA alone and on the alpha-AI-PPA complex. The results show that, in the complex, PPA is more sensitive to subtilisin attack, and shorter fragments are obtained. These data reflect the conformational changes undergone by PPA as the result of the protein inhibitor binding, which differ from those previously observed with acarbose.  (+info)

Psyllium shifts the fermentation site of high-amylose cornstarch toward the distal colon and increases fecal butyrate concentration in rats. (5/213)

We examined the combination effects of psyllium (PS) and resistant starch on large bowel short-chain fatty acids (SCFA). Rats were fed one of the following four diets: low amylose (LAS) or high amylose cornstarch diets (HAS, 50 g/kg diet) with or without 15 g PS/kg diet (LAS/PS and HAS/PS diets). HAS and/or PS were substituted for the same amounts of LAS in diets. Cecal butyrate concentrations were significantly higher in rats fed the HAS and HAS/PS diets than in those fed the LAS and LAS/PS diets. However, butyrate and total SCFA concentrations in rats fed the HAS diet decreased along the length of the colon and fecal butyrate concentration was reduced to one-third of that in the cecum. In contrast, the HAS/PS diet maintained higher butyrate concentrations throughout the large bowel. Fecal butyrate concentration in the HAS/PS diet-fed group significantly exceeded the sum of the concentrations in rats fed the LAS/PS and HAS diets. PS supplementation to the HAS diet significantly increased fecal starch excretion by 10 fold compared with that of rats fed the HAS diet. There was a positive correlation between fecal butyrate concentration and fecal starch excretion (r = 0.709, P < 0.0001). In a further experiment, ileorectostomized rats were fed the HAS and HAS/PS diets. From the difference in fecal starch excretion between normal and ileorectostomized rats, starch degradation by large bowel microflora in rats fed the HAS and HAS/PS diets was deduced to be 96% and 63%, respectively. These findings support the hypothesis that PS may delay the fermentation rate of HAS in the cecum and shift the fermentation site of HAS toward the distal colon, leading to the higher butyrate concentration in the distal colon and feces.  (+info)

Characterization and crystallization of an active N-terminally truncated form of the Escherichia coli glycogen branching enzyme. (6/213)

The prokaryotic glycogen branching enzymes (GBE) can be divided into two groups on the basis of their primary structures: the first group of enzymes, which includes GBE from Escherichia coli, is characterized by a long N-terminal extension that is absent in the enzymes of the second group. The extension consists of approximately 100 amino-acid residues with unknown function. In order to characterize the function of this region, the 728 amino-acid residue, full-length E. coli GBE, and a truncated form (nGBE) missing the first 107 amino-acid residues were overexpressed in E. coli. Both enzymes were purified to homogeneity by a simple purification procedure involving ammonium sulphate precipitation, ion-exchange chromatography, and a second ammonium sulphate precipitation. Purified full-length enzyme was poorly soluble and formed aggregates, which were inactive, at concentrations above 1 mg.mL-1. In contrast, the truncated form could be concentrated to 6 mg.mL-1 without any visible signs of aggregation or loss of activity on concentration. The ability to overexpress nGBE in a highly soluble form has allowed us to produce diffracting crystals of a branching enzyme for the first time. A comparison of the specific activities of purified GBE and nGBE in assays where amylose was used as substrate demonstrated that nGBE retained approximately half of the branching activity of full-length GBE and is therefore a suitable model for the study of the enzymes' catalytic mechanism.  (+info)

Mapping of genes for cooking and eating qualities in Thai jasmine rice (KDML105). (7/213)

Thai jasmine rice, KDML 105, is known as the best quality rice. It is known not only for its aroma but also for its good cooking and eating qualities. Amylose content (AC), gel consistency (GC) and gelatinization temperature (GT) are important traits determining rice quality. A population of recombinant inbred lines (RIL) derived from KDML105 x CT9993 cross was used to study the genetic control of AC, GC and GT traits. A total of 191 markers were used in the linkage map construction. The 1605.3 cM linkage map covering nearly the whole rice genome was used for QTL (define QTL) analysis. Four QTLs for AC were detected on chromosomes 3, 4, 6 and 7. These QTLs accounted for 80% of phenotypic variation explained (PVE) in AC. The presence of one major gene as well as several modifiers was responsible for the expression of the trait. Two QTLs on chromosome 6 and one on chromosome 7 were detected for GC, which accounts for 57% of PVE. A single gene of major effect along with modifier genes controls GC from this cross. The QTLs in the vicinity of waxy locus were major contributors in the expression of AC and GC. The finding that the position of QTLs for AC and GC were near each other may reflect tight linkage or pleiotropy. Three QTLs were detected, one on chromosome 2 and two on chromosome 6, which accounted for 67% of PVE in GT. Just like AC and GC, one major gene and modifier genes governed the variation in GT resulting from the KDML105 x CT9993 cross. Breeding for cooking and eating qualities will largely rely on the preferences of the end users.  (+info)

Suppression of extablished Friend virus leukemia by statolon: potentiation of statolon's leukemosuppressive activity by chlorite-oxidized oxyamylose. (8/213)

Treatment of Friend virus (FV)-infected mice, 3 days after FV inoculation, with statolon, an extract of the mold Penicillium stoloniferum, induces interferon and restores immunocompetence to viral and nonviral antigens such as sheep erythrocytes. Clinical remissions are established in 20 to 70% of the infected mice. Cholorite-oxidized oxyamylose administered intraperitoneally 24 h before, 3 h before, or 3 h after statolon enhanced interferon production, but the increased number of mice protected against FV disease was more closely related to the associated enhanced synthesis of FV cytotoxic antibody. The prolonged selective immunodepression to intraperitoneal sheep erythrocytes after intraperitoneal administration of chlorite-oxidized oxyamylose-statolon appeared to be related to a stimulation in number and erythrocyte-phagocytic capacity of peritoneal macrophages. The marked activation of macrophages in FV leukemic mice after such treatment may also have contributed to the enhanced FV leukemosuppressive effects of chlorite-oxidized oxyamylose-statolon.  (+info)

PY - 2001. Y1 - 2001. N2 - In this study, 3% aqueous high‐amylose maize starch (Hylon VII) dispersions were heated to temperatures of 140-165°C. The onset and rate of gel formation was observed using a small‐strain oscillation rheometer as a function of temperature from 90 to 25°C. The gel formation clearly began earlier in high‐amylose starch paste preheated at lower temperatures, but the rate of gelation was slower and the resulting gel was weaker in comparison with starch pastes preheated at higher temperatures. In addition, the structure of the final gels was studied using large deformation compression measurements. The most rigid gel structure on the basis of small and large deformation tests was obtained for high‐amylose starch gel preheated to 150-152°C, depending on the type of ...

Comparative study of film forming behaviour of low and high amylose starches using glycerol and xylitol as plasticizersComparative study of film forming behaviour of low and high amylose starches using glycerol and xylitol as plasticizers
In this study, the film forming behaviour of low amylose (LA) and high amylose (HA) starches was studied. The starch-alone and a blend of plasticizer (polyol)-starch films were developed by gelatinising at various temperatures and casting at 25 °C. The starch-plasticizer films contained glycerol and xylitol either individually or in 1:1 combination. The concentration of plasticizer used was 15%, 20% and 30% for LA films while it was 20%, 30% and 40% for HA films on dry solid basis. The HA-glycerol films retained the highest moisture content among all the films. The HA films exhibited higher glass transition temperature, higher tensile strength, higher modulus of elasticity and lower elongation at break than those obtained from LA starch. The tensile strength and modulus of elasticity decreased and the elongation increased with increasing plasticizer concentrations above 15% on dry solid basis regardless the starch type. Low water vapour permeability was evident in LA and HA films plasticized by ...

PY - 2004. Y1 - 2004. N2 - Amylose-glycerol films prepared by casting from solution were hydrated to different water contents. Wide-angle X-ray diffraction analysis suggested that the films were partially crystalline and contained the B polymorph. At a given hydration level, the presence of glycerol did not affect the extent of crystallinity or polymorphism of amylose. Proton NMR relaxometry was used to study the effects of water and glycerol on the molecular mobility of amylose. Spin-spin and spin-lattice relaxation parameters suggested a step change in the mobility of amylose when sufficient plasticiser, water and glycerol, was added to decrease the glass transition temperature (Tg) such that it became equal to or smaller than the observation temperature (T), i.e. (T−Tg)≥0. The mobility of amylose ...

Nuclear gene targeting | AlgentechNuclear gene targeting | Algentech
Starch is made of two homopolymers: amylose and amylopectin, themselves composed of D-glucose molecules. During the process of digestion, starch is dissociated into simple sugar molecules that are readily assimilated by the body. High amylose starch is more resistant to enzymatic digestion and is used as a food supplement for its high fiber content and low glycemic index. It is also used in the textile industry, cosmetic industry, pharmaceutical industry and the production of biodegradable plastics. We are currently working on the generation amylose-rich wheat lines. This is achieved by knocking out genes encoding starch-branching enzymes in the wheat genome. ...

Preparation and characterization of sorbitol modified nanoclay with high amylose bionanocompositesPreparation and characterization of sorbitol modified nanoclay with high amylose bionanocomposites
We investigate the influence of sorbitol and natural Na+-montmorillonite (nanoclay) loading on the characteristic of high amylose nanocomposites and the distribution of nanoclay after extrusion processing. The innovative aspect is the modification of the nanoclay using the sorbitol plasticizer, and as shown in the XRD results, good intercalated/exfoliated morphology had been achieved in all nanocomposites. The expansion of nanoclay gallery relates to sorbitol loading and nanoclay concentration. Evidence of newly formed hydrogen bonds, due to plasticizer and nanoclay interaction, and also the ternary interaction among starch/sorbitol/nanoclay were taken from peaks associated with -OH stretching located at 3300cm−1 and 999cm−1 from the FTIR spectra.

The intestinal microbiota may regulate bone metabolism by reducing levels of pro-inflammatory cytokines, and T cells in bone tissues of oestrogen-deficient mice have been reported. Resistant starch (RS) is a type of dietary fibre and results in changes in the composition of the gut microbiota. We evaluated the effects of RS supplemented in diets on intestinal microbial composition, bone mineral density, and inflammatory-gene expression in the colon and bone marrow of ovariectomised (OVX) mice. OVX mice were divided randomly into three groups: OVX control, OVX fed a 20% high amylose corn starch (HAS) diet, and OVX fed a 20% acid-hydrolysed HAS (AH-HAS) diet. HAS and AH-HAS diets contained 6.8% and 12% of RS, respectively. After 6 weeks, treatment with HAS or AH-HAS increased the abundance of Bifidobacterium spp. in faeces. The AH-HAS diet tended to upregulate mRNA expression of interleukin (IL)-10 in the colon, and downregulate expression of receptor activator of nuclear factor kappa-B ligand and IL-7

Novel hydrogel compositions of diester crosslinked polyglucans and a process for their preparation are provided. Amylose, dextran, and pullulan succinates and glutarates when crosslinked as described were found to not only have use as general fluid sorbants but also to have exceptional hemostatic activity, adherence to a wound, and bioabsorption without causing undue irritation of the tissue or toxic effects. Reticulated hydrogel sponges made of the crosslinked diesters which are particularly useful as general fluid sorbants, and those of amylose succinate and amylose glutarate are most excellent bioabsorbable hemostatic agents. The sponges are made by lyophilizing water-soluble salts of the mono- or half-esters, such as water-soluble salts of amylose succinate or amylose glutarate, under process conditions of the invention in the presence of a reticulating agent which causes a controlled melting of the salt solution as it nears the dry state during the lyophilizing step.

Purification yields protein complex between recombinant and native p97Purification yields protein complex between recombinant and native p97
Hi everybody, I have expressed a recombinant mouse protein, p97, in High Five insect cells using Gibcos baculovirus protocol. This is a fusion protein with Maltose binding protein at the N-terminal end. After purifying on amylose resin, I get very pure protein; only two bands show up by Coomassie staining. One is my recombinant fusion protein, MBP-p97, the other is the native p97 from the insect cells. Since p97 forms normally forms homohexamers, I assume the insect p97 is similar enough to complex with the overexpressed recombinant p97. Has anyone come across this problem? If so, I need ideas to get rid of the native protein. Amylose resin is not compatible with denaturing protocols and I would prefer not to have to try to renature to restore ATPase activity.

Single crystals of V-amylose complexed with fatty acids and ibuprofen - EMC AbstractsSingle crystals of V-amylose complexed with fatty acids and ibuprofen - EMC Abstracts
Amylose, a mostly linear homopolymer of α(1,4)-D-glucose extracted from native starch, has the ability to form crystalline inclusion compounds with a large variety of small molecules. In these crystallosolvates, the so-called V-amylose occurs in the form of single helices and the ligands can be located inside the helices, in-between or both [Lourdin et al., in Starch - Metabolism and Structure, Springer Japan, 2015, p. 61]. In this study, we have crystallized fractions of native and in vitro-biosynthesized amylose in the presence of various fatty acids and ibuprofen, a widely used anti-inflammatory drug [Yang et al., Starch-Stärke 65 (2013), 593]. The morphology, structure and stoichiometry of the resulting lamellar single crystals were characterized using TEM imaging, electron and X-ray diffraction, and solid-state NMR.. Dilute aqueous solutions of amylose (0.1 wt%) and fatty acids were briefly heated at 160°C, then kept at 90 or 100°C for 24 h. Crystallization occurred during the slow ...

Joining proteins together into multi-functional assemblies could be useful for improved diagnostic and therapeutic tools. However, it is tricky to link protein units with precise orientation. Also, if reversible bridges are used between the protein units, the assemblies can soon re-arrange or fall apart.. In 2012 Bijan Zakeri in the Howarth lab developed the SpyTag/SpyCatcher linkage system by re-engineering a protein from Streptococcus pyogenes. The approach here depended on Raphael Gayet in the lab creating a 2nd specific linkage from Streptococcus pneumoniae called SnoopTag/SnoopCatcher. Teams are formed by alternating SpyTag reaction with SnoopTag reaction on amylose resin.. The group decided to apply the new technology to synthesise controlled protein assemblies to induce cancer cell apoptosis. Team building just involves adding and washing, with each subunit expressed in bacteria. So we could produce lots of combinations for simultaneous stimulation of Death Receptors and various ...

Because farro is a robust, resilient grain that often takes hours to cook, most commercial farro is pearled-like barley-to reduce its cooking time. Pearling farro or barley means that once hulled, part of its bran layer is scalped off. When the bran layer goes, the flavor goes, too. What remains? A chewy plug of pure starch. Anson Mills pearls no farro.. Our work-around for farros long cook time comes with an overnight soak, during which time the amylase/amylose starch conversion begins and the farro will smell sweet and fresh. Once in the pot, it still takes its good time (a full hour), but picks up the perks of absorbing full-flavor homemade chicken stock infused with leeks and mushrooms..

Cornstarch - CAMEOCornstarch - CAMEO
White amorphous polysaccharide granules that compose about 70% of a corn kernel. Cornstarch is separated from the gluten and fibrous particles by sieving, wet grinding, then wash flotation. It is composed of 28% amylose and 75% amylopectin. When heated with water, cornstarch forms a medium viscosity solution that does not change with heating time. It thickens substantially on cooling to form an opaque gel. Cornstarch is the predominant starch used in North America as a thickener and filler in foods. It is used as an absorbent powder in baby powders and on the interior of some powdered latex gloves. Cornstarch is also used as an adhesive, a sizing agent, and a filler in waxes and plastics. ...

1. Enzymes are complex proteins produced by living cells that catalyze specific biochemical reactions usually at body temperature (98.6 F or 37 C). Enzymes are usually sold in powder form and are obtained from animal, plant (particularly fungal), and bacteriological sources. In addition to their source designation, enzymes are also described in terms of unit definition, activity, and purity.. 2. The α-amylases attack randomly along the amylose chain (the major component of wheat starch) to convert it into dextrins (short-chained polysaccharides), which are very water soluble. The β-amylases attack amylose only from one end at a time and are therefore much less effective compared to α-amylases. Diastases contain both α- and β-amylases and, therefore, are not as effective as the α-amylases alone. Proteases cleave the bonds of proteins leading to shorter chain polypeptides and finally to amino acid molecules, which are water soluble. Trypsins, which come from the ferments of pancreatic ...

Bcl‐2 regulator FKBP38 is activated by Ca2+/calmodulin | The EMBO JournalBcl‐2 regulator FKBP38 is activated by Ca2+/calmodulin | The EMBO Journal
Here, we demonstrated that the activity of FKBP38 is controlled by its association with Ca2+/CaM. Enzymatic activity was observed at calcium concentrations below 1 μM. Simultaneously, appearance of an FK506‐binding site in the heterodimeric complex was observed. In the absence of Ca2+/CaM, the enzyme remained completely inactive, and commonly known FKBP ligands, such as immunosuppressive and nonimmunosuppressive peptidomacrolides and their derivatives, failed to bind.. Our study provides the first example for a cofactor‐regulated folding helper enzyme. In order to verify enzyme activation by intracellular Ca2+ rise, the active site concentration of endogenous FKBP38 was determined by co‐immunoprecipitation and affinity absorption on MBP‐Bcl‐2 amylose beads. The inactive form of FKBP38 dominates in unstimulated SH‐SY5Y cells.. Near‐UV CD spectroscopy revealed activation of FKBP38 in the Ca2+/CaM/FKBP38 complex by changes of the tertiary structure‐related signals of the enzyme. As ...

Characterization of the Reactions of Starch Branching Enzymes from Rice Endosperm : Plant and Cell Physiology - oiCharacterization of the Reactions of Starch Branching Enzymes from Rice Endosperm : Plant and Cell Physiology - oi
To our knowledge the present paper shows for the first time the kinetic parameters of all the three starch branching enzyme (BE) isozymes, BEI, BEIIa and BEIIb, from rice with both amylopectin and synthetic amylose as glucan substrate. The activities of these BE isozymes with a linear glucan amylose decreased with a decrease in the molar size of amylose, and no activities of BEIIa and BEIIb were found when the degree of polymerization (DP) of amylose was lower than at least 80, whereas BEI had an activity with amylose of a DP higher than approximately 50. Detailed analyses of debranched products from BE reactions revealed the distinct chain length preferences of the individual BE isozymes. BEIIb almost exclusively transferred chains of DP7 and DP6 while BEIIa formed a wide range of short chains of DP6 to around DP15 from outer chains of amylopectin and amylose. On the other hand, BEI formed a variety of short chains and intermediate chains of a DP ≤40 by attacking not only outer chains but ...

Combined rheological and optical investigation of maize, barley and wheat starch gelatinisation - UQ eSpaceCombined rheological and optical investigation of maize, barley and wheat starch gelatinisation - UQ eSpace
Microstructural and rheological changes during gelatinisation are important indicators of starch functionality. A combined rheometer and optical microscope system (Rheoscope 1, Thermo Haake) was used to monitor the gelatinisation of different starches (maize starch containing 0%, 24%, 55% and 85% amylose; wheat starch and barley starch) suspended in a 0.1% guar solution (to minimise settling during the initial stages of gelatinisation). The 0.1% guar solution was selected after Rapid Visco Analyser, Modulated DSC and settling studies indicated that it minimised any effect on starch gelatinisation compared to carboxy methyl cellulose and xanthan. The Rheoscope study demonstrated that the viscosity of the starch during gelatinisation is related to changes in starch granules as a result of swelling. There was a two to threefold increase in starch granule size during the gelatinisation for all starches except for high amylose maize starches. Viscosity development during the gelatinisation was ...

Prediction of starch hydrolysis in native starches studied in vitro | Research UNEPrediction of starch hydrolysis in native starches studied in vitro | Research UNE
Starches from different botanical origin (sago, rice, wheat, corn, sweet potato, arrowroot, and potato as well as sweet potato meal, cassava pulp, and tapioca) with varying total starch (TS) and amylose content were assessed for hydrolysis in vitro by gastric enzymes and their starch fractions were characterized as rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS). The relationship between starch hydrolysis (SH) and organic matter digestibility, as well as total variability among TS, amylose content, RDS, SDS, and RS fractions of these test starches were also studied. SH varied significantly ranging from 9.8% in potato starch to 85.5% in sago starch with organic matter digestibility (OMD) of 22.36 and 95.04%, respectively. Significantly positive relationships were also recorded between SH and OMD, SDS, RDS and a significantly negative relationship with RS. Prediction equations were proposed to estimate SH from OMD and TS, and the correlation between ...

Wild Oryza grain physico-chemical properties by S Kasem, Daniel LE Waters et al.Wild Oryza grain physico-chemical properties by S Kasem, Daniel LE Waters et al.
Of the 22 species within the Oryza genus, only two, O. sativa and O. glaberrima, have been domesticated. Although food security is supported by accessing wild Oryza resources for new genes and alleles which enhance plant performance, wild Oryza grain properties have not been extensively studied. Evaluation of the grain physico-chemical properties of eight wild Oryza species found amylose content, amylopectin structure and cooking properties fell within a narrow range relative to cultivated rice. The amylopectin of the wild species had a lower proportion of short branch chains (DP 6-14) relative to cultivated rice and were all of high apparent amylose content and gelatinization temperature. The grain of the wild species did not elongate to the same extent as the cultivated rice and had lower viscosity parameters. These results highlight how significant physio-chemical changes have been made by human selection in the domestication of rice, especially japonica rice. The wild species may be useful for

The gelatinisation of starch in the presence of low levels of water and high levels of sucrose was studied. The gelatinisation temperature was found to increase in the presence of sucrose, whereas the gelatinisation enthalpy was unaffected. The gelatinisation temperature range was not as broad in the presence of sucrose as without sucrose. Furthermore, the shape of the gelatinisation endotherm was changed by the addition of sucrose. The double endotherm obtained in limited water-starch systems was changed into a single endotherm, similar to the endotherm obtained in excess water-starch systems at ...

Tensides or surfactants are amphiphilic organic compounds that consist of both hydrophobic and hydrophilic parts. Tenzides are used in food industry (bakery), pharmaceutical industry, chemical industry, etc. Amylose is an essential unbranched form of starch. It is composed of glucose units which are linked with α-1,4- glucosidic bounds creating a spiral chain in shape of a helix. Potentiometric titration of amylose (0; 0.1; 0.5; 1; 2 and 4%) with octadecyl-trimethyl ammonium bromide (4 x 10-3 moldm-3) was followed by the formation of inclusion complex by changing the critical micellar concentration. In amylose OTAB complex formation mechanism fatty hydrocarbon chain cationic surfactants OTAB enters the amylose helix.

GI Symbol News with Dr Alan BarclayGI Symbol News with Dr Alan Barclay
Starchy foods Unlike sugary foods, the type of starch contained in a food is not as strong a predictor of its GI for a variety of reasons. There are two main types of starch - amylose and amylopectin, with amylose having a lower GI than amylopectin. So a food with more amylose may have a lower GI than one higher in amylopectin, but this is not always the case. This is partly because the starches in unrefined grains like hulled barley, brown rice or wheat berries are encapsulated by the germ and bran, which when left intact can make the starch - regardless of type - very hard to digest. Of course, this is why we process them to provide us with more digestible forms (e.g. pearl barley, white rice and bulgur) or into flour. We have found that the milling method (e.g., stone grinding versus modern steel roller milling) generally has a more significant effect on the ultimate GI of grain foods. Traditionally stone ground flours retain much more of the germ and bran and have more coarsely ground ...

Preparation and characterization of glycerol plasticized (high-amylose) starch-chitosan filmsPreparation and characterization of glycerol plasticized (high-amylose) starch-chitosan films
The chitosan-starch (high amylose) blend film (1;1), via microfluidization, was prepared by casting with different glycerol concentration (0%, 2.5%, 5% and 10%). The films were characterized for their mechanical, thermal and morphological properties. The addition of glycerol at 5% (w/w) and higher concentrations resulted in decrease in tensile strength, increase in elongation at break due to plasticization. The wellknown antiplasticization was observed in the polymer films with 2.5% of glycerol. The addition of glycerol promoted the interactions among chitosan, starch and glycerol through hydrogen bonding as reflected on the shifting of main peaks of the glycerol-free film to higher wavenumbers as shown by FTIR spectra. The decrease in intensity of glycerol-related peaks in starch-chitosan-glycerol films in both 1H NMR and 13C NMR spectra proved the strong interactions (decrease in glycerol mobility) occurring among starch, chitosan and glycerol in glycerol-plasticized films. © 2012 Elsevier ...

Amylopectin - WikipediaAmylopectin - Wikipedia
Glucose units are linked in a linear way with α(1→4) glycosidic bonds. Branching takes place with α(1→6) bonds occurring every 24 to 30 glucose units, resulting in a soluble molecule that can be quickly degraded as it has many end points onto which enzymes can attach. In contrast, amylose contains very few α(1→6) bonds, or even none at all. This causes amylose to be hydrolyzed more slowly, but have higher density and be insoluble.[clarification needed]. Its counterpart in animals is glycogen, which has the same composition and structure, but with more extensive branching that occurs every eight to 12 glucose units. Plants store starch within specialized organelles called amyloplasts. When energy is needed for cell work, the plant hydrolyzes the starch, releasing the glucose subunits. Humans and other animals that eat plant foods also use amylase, an enzyme that assists in breaking down amylopectin. Starch is made of about 70% amylopectin by weight, though it varies depending on the ...

Starch is the most abundant storage glucan composed of two main structural components, amylose and amylopectin. Based on the rate of digestion, starch can be classified as rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS) (Shi and Maningat 2013). In recent years, the effect of RS has drawn increasing interests in that it is not digested in the upper gastrointestinal tract, but is fermented in the large intestine and is beneficial for the gut environment (Lafiandra et al. 2014). Our recent research has shown that the applications of RS in foods can moderate the glycemic response and maintain a proper microorganism profile in the human gut (Zhou et al. 2013a, b). It has also been found that RS with a slow absorption and a low glycemic index can reduce blood lipids and improve insulin sensitivity, which can improve the glucose intolerance and insulin resistance (Goda et al. 2014). Previous studies have also shown that RS can reduce cholesterol and ...

Genotype had a significant effect on protein and starch concentrations in pea and fababean, on pasting, trough, cooling and final viscosities of starch from pea and fababean, and on onset and peak temperatures of gelatinization of starch from fababean. Significant genotype x environment interactions were observed for the concentrations of starch in pea and fababean, the concentration of amylose, endothermic enthalpy and trough viscosity in starch from fababean, and pasting viscosities of starch from pea. The effects of genotype and environment on the physicochemical characteristics of starch from pea and fababean grown in western Canada would likely not be of practical significance. Native, heat-moisture-treated and pregelatinized blends of pea starch and starch from corn, waxy corn, high-amylose corn or potato exhibited a variety of functionalities due to differences in the functionalities of the constituent starches and to the effects of heat-moisture treatment and pregelatinization.

The genetically modified potato line show a shift of the tuber starch composition to amylose. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats compared to conventional potato varieties is expected. Nor is it expected that a selective advantage or disadvantage is conferred to the GM lines via the introduced traits. Due to the measures to be taken during the release (distance to or absence of cultivated and wild relatives) will the potential for gene transfer virtually be excluded. Interactions of the GM potato lines with non-target species and resulting effects will be comparable to those of conventional potato varieties. No toxic or allergenic effects are expected from elevated levels of amylose, nor from the nptII gene. Measures in place under current field trial practice will safeguard that all tubers and plant material is properly managed, harvested, stored, transported or disposed of to minimize contact to humans or animals.

DISCUSSION. Dietary nutritional requirements of two species of penaeoids were investigated on the basis of their haemolymph metabolic contents and the apparent digestibility analysis to determine which the dietary components that were better assimilated are. The penaeoids shrimp do not present a dietary glucose requirement since this compound can come from the gluconeogenesis from the amino acids. Nevertheless, these organisms own a complete enzymatic structure for the digestion of proteins and polysaccharides, such as starch, glycogen, laminarin, and chitin that are natural components of their diet. (Tacon, 1990). The starch is a straight-chain consisting of glucose molecules linked together by a (1-4) bonds, conformed by two units amylose and amylopectin. The starches rich in amylose are poorly digestible because a-amylase cannot hydrolyze the amylase, in contrast, the starch rich in amylopectin is relatively well digested (Gaxiola et al., 2006). The cellulose is also a polymer of glucose but ...

There is growing interest in the research of resistant starches. Most of the carbohydrates in the diet are starches, which are long chains of glucose found in many foods. Not all of the starch we eat gets digested. During the digestive process, some of the starch doesnt get processed because it is resistant to digestion.. This is exciting news because until now, carbohydrates was shunned, leaving many of us hungry and cranky in an effort to watch our weight and health. However, foods that are rich in resistant starches act similar to soluble fiber and help solve many digestive problems. They do not cause spikes in blood glucose or insulin after being eaten and they provide substantially fewer calories. Research has found that resistant starch can trigger hormonal response that makes us feel more satisfied, lowers blood sugar levels, improves colon health and lowers the risk of cancer. There are 4 different types of resistant starch.. Type 1 is found in oats, barley, grains, seeds and legumes ...

Physically modified extruded flours are suitable ingredients for cold preparation of products such as creams and sauces. The rheological and textural properties and stability of model sauces prepared with wheat and rice extruded flours with three different particle size fractions were assessed. All tested sauces showed non-Newtonian, shear-thinning and thixotropic fluid characteristics. Sauces made with rice extruded flours, with lower protein and amylose contents, presented lower shear-thinning behaviour, consistency index and yield stress than wheat based sauces. Rice sauces also displayed a less compact microstructure and lower viscoelastic character but a higher resistance to freeze-thaw process. Regarding particle size, the finest flours showed lower values of consistency index, yield stress, and G and G moduli but led to higher syneresis. Overall, results proved that pregelatinised extruded flours can be used in sauces applications without heating, but their properties greatly depend on ...

Vitamins May Hitch A Protected Ride On Corn Starch - RedorbitVitamins May Hitch A Protected Ride On Corn Starch - Redorbit
Vitamins and medications may one day take rides on starch compounds creating stable vitamin-enriched ingredients and cheaper controlled-release drugs, according to Penn State food scientists.. The technique may offer drug and food companies a less expensive, more environmentally friendly alternative in creating, among other products, medications and food supplements.. In a series of experiments, researchers formed pockets with corn starch and a fatty acid ester to carry oil soluble vitamins, such as vitamin A and vitamin C, into the body, according to Gregory Ziegler, professor, food sciences.. Heat and acids can harm or destroy vitamins. The starch molecule forms a protective pocket around the vitamins as they travel through the highly acidic stomach and into the small intestines, where they can be absorbed into the blood stream.. To form the pocket, the researchers, who released their findings in a recent issue of Carbohydrate Polymers, used a type of corn starch called high amylose maize ...

Since cancer cells depend on glucose more than normal cells, we compared the effects of low carbohydrate (CHO) diets to a Western diet on the growth rate of tumors in mice. To avoid caloric restriction-induced effects, we designed the low CHO diets isocaloric with the Western diet by increasing protein rather than fat levels because of the reported tumor-promoting effects of high fat and the immune-stimulating effects of high protein. We found that both murine and human carcinomas grew slower in mice on diets containing low amylose CHO and high protein compared with a Western diet characterized by relatively high CHO and low protein. There was no weight difference between the tumor-bearing mice on the low CHO or Western diets.. Additionally, the low CHO-fed mice exhibited lower blood glucose, insulin, and lactate levels. Additive antitumor effects with the low CHO diets were observed with the mTOR inhibitor CCI-779 and especially with the COX-2 inhibitor Celebrex, a potent anti-inflammatory ...

BPD is known to induce a greater weight loss than LAGB, independently of initial BMI; this information comes from a meta-analysis [25] and from two comparative studies [27, 28]. This finding was confirmed in the present study. Surgery was clearly more effective than control treatment, as already reported in the only study including control patients [21]. The pattern of BMI depicted in Figure 1 indicates that our findings were representative of what happens with the two surgical procedures. In agreement with two small studies [27, 28], the effect on metabolic variables, and the disappearance of diabetes mellitus (patients were treated with metformin, when required) were not different for the 2 procedures. Also disappearance of metabolic syndrome was not different. As to metabolic effects, the only difference was in cholesterol decrease, which appears more due to the technique than to amount of weight loss.

Resistant Starch: Medicinal Extreme SuperfoodThe Hackers HangoutResistant Starch: Medicinal Extreme SuperfoodThe Hackers Hangout
Tim-you make some interesting points, but I think your slant on pharma is overly paranoid (and I sure would want such things as fecal transplants regulated if I were going to have one!). At least with pharmaceutical products, they have to demonstrate safety and efficacy-two things that are never proven with supplements because they are not regulated in the same way, and supplement manufacturers and food manufacturers routinely make claims (along with disclaimers about the claims) without proving efficacy. You are leading the effort to measure amounts of resistant starch, which is terrific, but I would like to see more proof (like clinical trials) showing how resistant starch helps improve specific disease conditions, and I imagine that needs to happen before drug companies will be really interested. I can find studies on PubMed, usually claiming benefits in terms of weight loss, insulin resistance, and colon health, but they seem to be similar to benefits conferred by eating a high-fiber diet. ...
