The initial blue colour of the mixture turns green‚ then yellowish and may finally form a brick-red precipitates in the presence of reducing sugars. The amount of ppt gives a rough indication of the amount of reducing sugar present. Iodine test for starch Starch is slightly soluble in water in which it forms a colloidal solution. A blue-black colour indicates the presence of starch due to the formation of complex

Experiment no. 1: PHYTOCHEMICAL SCREENING INTRODUCTION Phytochemicals are define as the chemical compounds found or produced by the plants. The term is also define as the chemicals from the plant that may affect health [1]. This compounds are non-essential compounds which means that they are not required by the human body for sustaining life. There are more than thousand known phytochemicals. Some of the well-known phytochemicals are lycopene in tomatoes‚ isoflavones in soy and flavanoids in

Unfortunately‚ the increase in PPT was transient in that it decreased‚ with no regard to the treatment‚ during the fifteen minutes that were post-intervention. Aboodarda and colleagues postulated that the most likely explanation for the reduced PPT is possibly the effect heavy tissue massage had on the central pain-modulatory systems. To be more specific‚ the pressure of the massage provided

I. Abstract The experiment: Classification tests on Organic Compounds‚ allows the students to be familiarized with different classification tests used for identifying the different classes of organic compounds; examine unknown compounds using appropriate tests; and identify functional group of an organic compound based on the tests performed. Several organic compounds with different functional groups were tested to identify the functional groups present in the compound. n-heptane‚ pentene

Biology 101 1 November 2013 Cellular Respiration in Peas Part A: Abstract: This report examines Cellular Respiration and its functions as well as its function in germinating and non-germination peas. Cellular Respiration can best be described as a complicated string of chemical reactions. The complete Cellular respiration process begins with Glucose being oxidized‚ and the potential energy is transferred to the ATP molecule. The ATP molecule is now free to supply energy to the various

disodium hydrogen phosphate solution is added. Then shaken and rubbed the wall of test tube. If white ppt is formed the Mg2+ is present. Mg2+ + NH4Cl + NH4OH + Na2HPO4 →Mg(NH4)PO4 ↓ + Na+ + H2O Magnesium Ammonium Phosphate Test for Aluminum: Taking 20ml of stock solution in a flask & then added 10ml of NH4OH.Then a white gelatinous ppt is formed which indicates the presence of Aluminum.
