I have questions about biochemistry
would you give the answers?
1 . On the basis of titration data , why might it be difficult to distinguish between lysineand tyrosine ?2 . What is the PH of each of these solutions ? ( 2 10 MHNO3 ( 6 ) 6.21 10 M HCI3 . The prevailing structure of the molecule in the one of the unknown amino acidsolutions used in the experiment before titrating with NaOH isCOO -H 3 NHCHWhat is the structure after the amino acid is titrated with NaOH4 . Why is it important to ensure that the magnetic stirrers does not hit the pI meterelectrode5 . Consider the amino acid having pKa’s of 3 90 and 9 90 . What is its pi6 . Why it is important to calibrate the PH meter before the titration ?
