The effect on the structure of hemoglobin by the substitution of valine in place of glutamic acid is to be explained. Concept introduction: Hemoglobin is an oxygen carrying pigment made up of four heme groups that surrounds the globin group. Heme Group contains an iron atom which is responsible for the red color to the molecule. In sickle-cell disease, hemoglobin S is found. It is a type of anemia in which oxygen is in short supply and all the red blood cells become sickle-shaped. Hence, it is known as sickle-cell anemia. To determine: The effect on the structure of hemoglobin by the substitution of valine in place of glutamic acid.

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
