Paper electrophoresis of Asn, Ala, Asp, Lys and Ser mixtures at pH = 7 shows the fastestmovement towards the anodeThe fully saponified 10g oil sample consumed 1.87g KOH, and the iodine value of the oil was 28.3.So how many unsaturated double bonds are there in each oil molecule on average? (lodine isknown to have an atomic weight of 127)Given that 100g cellulose sample is completely hydrolyzed to obtain 78g glucose, then thepercentage of cellulose in the sample is _%Given that the Km of catalase is 20mmol/L and the substrate concentration is 80mmol/L, thenthe percentage of catalase bound to the substrate is %
