resistant starch type V Formation in brown lentil lens culinaris medikus starch with different lipids fatty acids
Food Chemistry, 2018Co-Authors: Bahar Nur Okumus, Zeynep Tacercaba, Kevser Kahraman, Dilara NilufererdilAbstract:This study aimed to characterize the brown lentil (Lens culinaris Medikus) starch and inVestigate the Formation of amylose-lipid complexes (Resistant Starch Type V) by the addition of different lipids/fatty acids (10%, w/w) to both raw and cooked starch samples. Resistant starch content (measured by the official method of AACCI (Method 32-40), using the resistant starch assay kit) of raw brown lentil starch (BLS) increased significantly by the additions of lipids/fatty acids, starch sample complexed with HSO (hydrogenated sunflower oil) (14.1±0.4%) being the highest. For the cooked starch/lipid complexes, more profound effect was eVident (22.2-67.7%). Peak, breakdown and trough Viscosity Values of the amylose-lipid complexed starches were significantly lower than that of BLS (p<0.05), while significant decreases in the setback and final Viscosities were only detected in oil samples, but not in fatty acids. Each lipid in concern exerted different effects on the digestibility of starch and amylose-lipid complex Formation while haVing no substantial differential effects on the thermal properties of starch depicted by differential scanning calorimetry (DSC). Amylose-lipid complex Formation with suitable fatty acids/lipids seems a promising way of increasing resistant starch content of food formulations. Although the applications being quite uncommon yet, brown lentil seems to haVe potential both as a starch and also as a resistant starch source.

Plants face the flow in V Formation: A study of plant patch alignment in streams
Limnology and Oceanography, 2019Co-Authors: Loreta Cornacchia, Andrew Folkard, Grieg Davies, Robert Grabowski, Johan Koppel, Daphne Wal, Geraldene Wharton, Sara Puijalon, Tjeerd BoumaAbstract:Interactions between biological and physical processes, so‐called bio‐physical feedbacks, are important for landscape eVolution. While these feedbacks haVe been quantified for isolated patches of Vegetation in aquatic ecosystems, we still lack knowledge of how the location of one patch affects the occurrence of others. To test for patterns in the spatial distribution of Vegetation patches in streams, we first measured the distance between Callitriche platycarpa patches using aerial images. Then, we measured the effects of Varying patch separation distance on flow Velocity, turbulence, and drag on plants in a field manipulation experiment. Lastly, we inVestigated whether these patterns of patch alignment deVeloped oVer time following locations of reduced hydrodynamic forces, using 2‐yr field obserVations of the temporal patch dynamics of Ranunculus penicillatus in a lowland chalk stream. Our results suggest that Vegetation patches in streams organize themselVes in V‐like shapes to reduce drag forces, creating an optimal configuration that decreases hydrodynamic forces and may therefore encourage patch growth. Downstream patches are more frequently found at the rear and slightly oVerlapping the upstream patch, in locations that are partially sheltered by the established upstream Vegetation while ensuring exposure to incoming flow (important for nutrient aVailability). ObserVations of macrophyte patch dynamics oVer time indicated that neighboring patches tend to grow in a slightly angled line, producing a spatial pattern resembling the V‐Formation in migratory birds. These findings point to the general role of bio‐physical interactions in shaping how organisms align themselVes spatially to aerodynamic and hydrodynamic flows at a range of scales.

Electrocatalytic oxidation of methanol by the [Ru3O(OAc)6(py)2(CH3OH)]3+cluster: improVing the metal-ligand electron transfer by accessing the higher oxidation states of a multicentered system
Química Nova, 2010Co-Authors: Henrique E. Toma, Koiti Araki, André Luiz Barboza Formiga, Anamaria D. P. Alexiou, Genebaldo S. NunesAbstract:The [Ru3O(Ac)6(py)2(CH3OH)] + cluster proVides an effectiVe electrocatalytic species for the oxidation of methanol under mild conditions. This complex exhibits characteristic electrochemical waVes at -1.02, 0.15 and 1.18 V, associated with the Ru3III,II,II/Ru3III,III,II/Ru 3III,III,III /Ru3IV,III,III successiVe redox couples, respectiVely. AboVe 1.7 V, Formation of two RuIV centers enhances the 2-electron oxidation of the methanol ligand yielding formaldehyde, in agreement with the theoretical eVolution of the HOMO leVels as a function of the oxidation states. This work illustrates an important strategy to improVe the efficiency of the oxidation catalysis, by using a multicentered redox catalyst and accessing its multiple higher oxidation states.
