Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Many of these effluents contain high level of toxic pollutants such heavy metals which are mainly produced by anthropogenic activities such as smelting‚ battery and steel manufacturing‚ mining‚ and metal processing (Verma and Dwivedi‚ 2013). The pollution caused by the release of these heavy metals into

Abstract (1‚3)-β-D-Glucans are naturally occurring polysaccharide polymers found in the cell walls of various fungi and bacteria. They are structurally composed of D-glucose polymers consisting of linear (1‚3)-β-D-glucosidic linkages of varying length and also branched polymers with side chains attached as (1‚6)-β-D-linkages. These side chains can be (1‚3)-β or (1‚6)-β glucoside chains of varying length. β-Glucans belong to a class of drugs called biological response modifiers (BRMs) due to their

No‚ no I should not. Essentially‚ by combining guar gum and borax you can create slime. If that’s all you want to know‚ that’s okay. Usually‚ these names are not found on packaging‚ but by their scientific names. Guar gum is also known as polysaccharide‚ and borax is called sodium borate. This is why some people use eye drops as part of their slime solution. Eyedrops have sodium borate‚ which when mixed with glue (and occasionally baking soda) creates slime! The other option is borax‚ which can

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

used to determine the identity of the unknown solution. The macromolecules being tested in this lab were carbohydrates (monosaccharides and polysaccharides) and proteins. To identify the presence of these macromolecules in a substance‚ three different tests were performed. Lugol ’s iodine solution was used for identification of starch and glycogen - polysaccharides - in the twelve solutions. A positive outcome of the test results in a colour change; blue-black in the presence of starch and a red-brown
