Macromolecules are large molecules known as polymers that are composed of repeating subunits known as monomers. There are four classes of macromolecules that perform a variety of tasks and functions for the maintenance of cells and biological life....
which forms water-insoluble globules consisting of many starch molecules. (b) A small section of a single starch molecule, which occurs as branched chains of up to half a million glucose subunits. (c) The precise
The social self-sorting supramolecular assembly is described by non-covalent interactions among four organic components. Toward this goal, a series of self-sorting systems have been investigated by mixing two or three different compounds; naphthyl-bridged bis(-cyclodextrin), N,N′-dioctyl-4,4′-...
The thermosphere is characterized by extremely thin air, with gas molecules spread so far apart that they rarely collide. Despite the sparse atmosphere, temperatures in this layer can soar to as high as 4,500 degrees Fahrenheit. This intense heat is primarily due to the absorption of high-energ...
It is unclear why size fractionation usually resulted in the loss of activity in both the large and small fractions. It could be that compounds were lost on the filter or that molecules of differing sizes work synergistically to induce settlement and without one or the other, the effect is le...
We screened a large number of chemically synthesized two-stranded and three-stranded constructs of the twister-sister ribozyme, before identifying a two-stranded construct composed of a four-way junctional fold shown schematically in Fig.1a, that yielded diffraction quality crystals. Cleavage assays on...
2. In Fig. 2a, we identify 10 major classes of substrates that are being transported by SLCs and we also define classes for orphans (substrate is unknown) and other (substrate that does not fit into any of the 10 classes). In Fig. 2b we display the number of TM regions that the ...
In this experiment, our chemistry team used theGo Direct Conductivity Probeto analyze the components of sports drinks commonly used by athletes to replenish electrolytes and water lost during physical activity and determine which molecules or ions are responsible for the conductivity of solutions. ...
organic snow and the potential for an interior ocean, Triton is an exciting exploration target to understand how habitable worlds may develop in our solar system and others. Using a single flyby, Trident would map Triton, characterize active processes and determine whether the predicted subsurface ...
The organic phase was washed with saturated aqueous NaHCO3, NaCl, and dried over anhydrous Na2SO4. After evaporation, the residue was purified by flash column chromatography using ethyl acetate-hexane (1:10˜5) as the eluent to afford 2 as a white solid (2.89 g; 62% yield): 1H NMR ...
