PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide sugars of varying

column on Table 3‚ the most effective step with regard to the percent of remaining protein removed was affinity chromatography because it was able to remove 98.6% of the remaining proteins. In comparison to 81.93% removed during the 65% ammonium sulfate precipitation and 81.3% during the size exclusion. This means that the affinity chromatography removed a big percentage of contaminating proteins. However‚ removing this huge amount of protein left us with a small amount of LDH and cost us a considerable

Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction The conversion of solid waste (waste glass) and fibers (bamboo fibers) into construction materials and its capability to fight against chemical weathering will be discussed in this study. Now a day‚ it is an exciting and innovative technology in the field of engineering. There are many studies had been formulated by researchers on how to minimize or be free in concrete deterioration in an economical way and some are using high-cost materials

IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in

BIOT6008 Environmental Biotechnology Lecture 3 Environmental Biotechnology Sources of Carbon The Earth’s Crust: The largest amount of carbon on Earth is stored in sedimentary rocks. Oceans: most in the form of dissolved inorganic carbon stored at great depths. A much smaller amount of carbon is located near the surface. Atmosphere: Mostly in the form of CO2. This carbon is of vital
