identified as Histidine by using a thin layer chromatography. Among the four amino acid standards (Ala‚ Gly‚ His‚ and Ser)‚ the average Rf value of the unknown (0.31) was closest to that of standard Histidine (0.29) and its Rf percent error was lowest (6.9%). Furthermore‚ the color‚ shape‚ and size of the unknown clearly corresponded to that of Histidine standard. Overall‚ the experiment was successful in identifying the unknown amino acid‚ for the obtained Rf and color were very distinct from each other

Andrews July 13‚ 2013 * * * * Abstract: In this laboratory we utilize simple measures of physical quantities (for example‚ distance‚ and mass) and use the measurements to calculate or convert other physical quantities (such volume and area). We also use mathematical calculations and formulas to make conversions from one unit of measurement into another unit of measurement (for example‚ a
