Figure 1: Schematic illustration of the principle of Biacore SPR to measure the interaction between analyte molecules in the flow with immobilized receptor binding sites on the surface. A) SPR uses an optical method to measure changes in the refractive index near the surface of a thin gold film on a glass slide. At a critical angle of incident light on the surface-solution interface an electromagnetic field or evanescent wave is generated. This is detected as absorption of light and a decrease in

Summary of Carbohydrates: Monosaccharides‚ Disaccharides‚ Polysaccharides Carbohydrates are molecules that are synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch

1.) Explain why the following substances are added to soil by gardeners and farmers. a.) Lime CaO It increases the pH of soil.Soil that is too acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

ABSTRACT ------------------------------------------------- Food contains nutrients that are very significant to the body. The basic essential nutrients‚ vitamins‚ and minerals play very significant functions in the different metabolic processes. In order for the nutrients to be known‚ several tests were performed to qualitatively analyze nutrients for the different food samples. Reagents were used as indicators to test common food substances for the presence of specific nutrients. Fruit juice

1. Impact of Environmental Tobacco Smoke (ETS) on non-smokers 2. Introduction During teenage years‚ most people find tobacco smoking “cool” and trendy; this could be attributed to the characteristic chemistry of some compounds found in the tobacco plant‚ which enhance moods and increase energy levels by stimulating the release of endorphins which reduce pain perception and trigger positive feelings (Jenkins & Guerin 2000); and peer pressure. As “cool “and trendy as tobacco smoking may
