Effect Of Inhibitors On Trypsin Activity

INTRODUCTION
The purpose of the experiment was to study the effect of P-BAPA on the hydrolytic enzyme trypsin and to insure at the effect of the competitive inhibition from chicken ballock white. To do so, the technique used for the effects of inhibitors on trypsin operation was the spectrophotometer used to measure absorbance of P-nitro aniline as a buy the farm of concentration in order to get a modular snub. Absorbance of p-nitrroaniline was used as a probe for all reaction.

METHODS;
The experiment was performed by firstly adding enzyme to the substrate; the solution was the product and lover reading taking respectively. The spectrometer was turn on and pock to and absorbance reading of 405nm. Also, five tubes were set up containing different sum up of standard of 50?M P-nitro aniline solution, a flick of3ml (0.05M, Tris, PH 9.2) and 300?l BAPA (4.6mg/ml in DMF) was shed in a solvent resistant cuvette and placed in the spectrophotometer to take 5 (five) different reading of the standard curve for P-nitro aniline using it as a blank.




The next ill-treat was to determine the initial reaction rate in the carriage of inhibitor, which shows the activity of the trypsin in the presence of varying amount of inhibitors, by doing so, 200?l of trypsin was added (1mg/ml in buffer) to the three cuvette effrontery to perform the experiment which contained buffer and BAPA and mix. The cuvette was placed into the spectrophotometer by showtime the stop watch and recording the OD reading all 30 seconds for 5 (five) minutes. Whiles the cuvette remains in the machine for the total 5 minutes and noting the value every 30 seconds as given in the instruction. The process was repeated by using a clean cuvette severally time but in the presence of different amount of trypsin inhibitor (stock solution of 0.1mg/ml in buffer).and by putting the mix in a beaker each to avoid melting/dissolve any plastic. And in each case of the mix, the BAPA was the last solution that was added to the cuvette. The...If you want to get a full essay, order it on our website: Orderessay
