Hello students so in this question we have to tell that which of these statements about amino acids are true okay, so let's read first statement in the first statement we are given that an amino acid at least have one amino group and one carboxyl growth okay, so what constitutes an amino acid let's see this is our amino acid and its basic structure is it has one variable side are represented by our one is hydrogen and another two are one is carboxyl and and then one is amino group.
00:32
So one is nh2 and another is carboxyl group that is c -o -h.
00:38
So this is our typical amino acid structure.
00:42
In this amino acid only this are hydrocarbon term is variable and these are constant.
00:47
So first statement is true.
00:48
It has at least one amino group and at least one carboxyl group.
00:54
Okay.
00:55
Moving on to the next statement.
00:56
The next statement says that the variable side chains of all the amino acids are highly reactive and carry a charge at neutral ph.
01:03
The variable side change that is r.
01:05
So r is a hydrocarbon part.
01:08
Hydrocarbon.
01:10
It does not carry any charge at any ph because it is made of hydrocarbons.
01:15
It's just carbon and hydrogen only.
01:18
Sometimes it can be, it can also be also contain nitrogen and oxygen too, but most of the times it is carbon and hydrogen.
01:26
So this statement is wrong.
01:28
So first statement was correct.
01:34
The next statement is, in the third statement, the question is, sorry, this third statement says that the peptide bone that bones the amino acids together is a type of ionic bone, which means that proteins are unstable at high temperatures...
