So a polypeptide chain that makes up a protein is made up of peptide bonds between amino acids.
00:19
So the polypeptide chains are formed by the polymerization of amino acids where the amino acids are the building blocks of each polypeptide chain which make up the protein.
00:32
So if we consider, that is the formation of a peptide bond or the formation of a dipeptide.
00:42
So in that case, two amino acids will undergo dehydration to form a diepeptide.
00:51
So let's consider this as amino acid one.
00:55
So the structure of amino acid one can be shown as follows.
00:59
So this is the carboxyl group, an amino group, a hydrogen atom, and then are side chain present in the amino acid 1.
01:10
And if we consider another amino acid as the amino acid 2, then the structure of this will be an h2, an amino group, a carboxyl group, another hydrogen atom and another r chain.
01:30
So if the formation of a peptide bond takes place, then dehydration takes place, that is a removal of a water molecule, occurs during peptide bond formation.
01:44
So we'll get the following dye peptide.
01:49
So we have an alpha carbon, a carboxyl carbon to which the o bond is attached and nitrogen atom of the next amino acid.
02:01
So this is the dye peptide that is formed between two amino acids.
02:24
And this bond that is formed between the carboxyl group of one amino acid and the amino group of the second amino acid is known as the peptide bond.
02:40
Also a molecule is formed along with the dye peptide.
02:46
So therefore this is a dehydration reaction...
