Is given 9.1 and log of 40% is the conjugate base And we have six peoples and of the week asset at this ph So we can solve with us. Plus log of conjugate conjugate base concentration of consecrated piece divided by concentration of weak acids. And then in the next part we have to find out that what is the ph So here we can use the Henderson habitual Henderson equation. Find the value of pH where the net charge is zero and the average closest pKa value on. So Be at 7.3 is the ph where we can find this winter iron form of data racine then see part is net charge of two negative. A general thumb rule that works for peptides also works for amino acids. Part asked that at what P etcetera informs.
b) X could have a pKa value less than 7.0. So let's try to solve the other parts of the question. X could have a pKa value greater than 7.0 for a non-polar R-group. I'm the sweater I informed has a net charge of zero. So here we have the structure at in it at a ph 10.7 if we talk about the charges, so net charge In this structure is -2. Now if you further Move towards more basic ph that is 10.7 at this time we will have a game during But from here oh mine hydrogen will be removed and we will have Two negative charges, one from carb oxalic acid and other one from the group. So here the ring will have which as it is what here We will have the NH two group and hydrogen will be removed from car box like acid. But we will have more pro terminated NH two group.
The edge here what at the other end, the carb oxalic acid will also remain the same. So in this case benton link will remain the same. Now, if we move towards slightly more acidic ph that is at 2.2 he hit there is more concentration of H plus iron. I am a proton removed both in this structure. Background Accurate estimation of the isoelectric point (pI) based on the amino acid sequence is useful for many analytical biochemistry and proteomics techniques such as 2-D polyacrylamide gel electrophoresis, or capillary isoelectric focusing used in combination with high-throughput mass spectrometry. The titles didn't exist as a twitter I inform that is having both positive and negative charges on it. No, at neutral ph r P H That is equal to 7.3. And then we have our box like asset growth And NH two. Here, p I of Lysine is p I of Lysine9. And this question we have tyros in and we have to discuss various structures of tyrosine at different page in the first part, two titles in the basic molecule is Having a Benjamin Ring and which group at one end. Solution Verified by Toppr Correct option is B) Isoelectric point of amino acid is defined as the p H where there are no effective charges.
