So this question we need to know about the basic structure of amino acid.
00:06
So amino acid is a fundamental unit of a protein.
00:09
So what it contains is amino acid contains a carbon atom, a carboxyl group, nh2 group that is amine group, a hydrogen ion and then it has an r group.
00:23
So this is the basic structure of amino acid.
00:26
So amino acid, what happens? the first question is what happens to the amino acid? with a ph 3.
00:32
So we know ph 3 which is acidic ph happens only when there is a increased hydrogen ion concentration.
00:42
So what happens to the amino acid here is the amino acid is protonated which means it gains a hydrogen ion in their amine group.
00:51
So a hydrogen ion is added so the net charge is positive.
00:57
So the answer is when the ph is 3 the ion amino acids are positively charged.
01:07
So this is the correct answer for the first question.
01:10
So let's go to the second question.
01:12
What happens to the amino acid with the ph is 11, which is alkaline ph.
01:19
So in alkaline ph or when the ph crosses the 7 mark, there is a decrease in hydrogen ion concentration...
