Students so in this question we have so the correct statements are the statement first that is serene and therine are polar amino acids that is serine and therone and therio9 are polar amino acids or polar amino acids 3 .9 has more than one stature center that is chiral center that is 309 has more than one stereo center then one stereo center.
00:49
Coming up to the third part, that is as follows.
00:54
The lusine side chain does not form hydrogen bond.
00:57
The lusine side chain does not form hydrogen bonds, that is, hydrogen bonds with other amino acids with other amino acids so with these are all the statements which are correct that is at ph 7 .4 at p .7 .4 chleu sign has overall charge 0 to first that is that is at ph 7 .4 lusine has zero charge so the first statement is sorry incorrect the first statement is incorrect that is this statement yeah so coming up to the next that is a methionine does not contain the methanol does not contain rss group in it so mito9 is not a thyroid so second statement is also false.
02:12
That is r s h is also false.
02:16
These are the statements that are correct but the sequential statements that is first and second are incorrect.
02:23
Why? because this is a thial.
02:25
The second statement is thyl and ethionine does not contain rss group because it is not a thialol.
02:31
Third statement that is the serine and a three inine are polar amino acid as they carry a hydroxyl group...
