Ecology, Biodiversity & Evolution-I:
Prepare a buffer solution of pH 7.2 by mixing 36 mL of sodium hydrogen phosphate (5 mM) and 14 ml of sodium dihydrogen phosphate (5 mM) and diluting with distilled water to 1000 Jr. This buffer is used to prepare a 1% azocasein solution. 5% aqueous solution of trichloroacetic acid was also required.

BT101 MIDTERM PAST PAPERS:
Determination of protease activity. The test for proteolytic activity involves mixing 1 ml of azocasein solution with 100 ml of the sample that contains the enzyme. The contents of the tubes are mixed and incubated at 35.5°C for 15 minutes. The reaction is stopped by adding 2 ml of 5% TCA. The absorbance of the supernatant is recorded at 345 nm in a UV/Visible spectrophotometer.
BT101 MIDTERM PAST PAPERS BY MOAAZ :
Potassium iodide solution is added to reduce excess ICl to free iodine. The released iodine is then titrated with a standardized sodium solution thiosulphate using a starch indicator and the iodine number is calculated.
BT101 MIDTERM SOLVED PAPERS:
The iodine number is defined as the grams of iodine absorbed per 100 grams of sample. The higher the amount of unsaturation the more iodine is absorbed. The amount of fat or oil dissolved in the solvent reacts with a measured amount of iodine or other halogens. Halogen addition of double bonds occurs.
