During the formation of the peptide bond which of the following takes place?
|
|
Hydroxyl group is lost from its carboxyl group of one amino acid and a hydrogen atom is lost from its amino group of another amino acid
|
|
|
Hydrogen atom is lost from its carboxyl group of one amino acid and a hydroxyl group is lost from its amino group of another amino acid
|
|
|
Hydroxyl group is lost from its carboxyl group of one amino acid and a hydroxyl group is lost from its amino group of another amino acid
|
|
|
Hydrogen atom is lost from its carboxyl group of one amino acid and a hydrogen atom is lost from its amino group of another amino acid
|
Explanation:
Detailed explanation-1: -During the reaction, one of the amino acids gives a carboxyl group to the reaction and loses a hydroxyl group (hydrogen and oxygen). The other amino acid loses hydrogen from the NH2 group. The hydroxyl group is substituted by nitrogen thus forming a peptide bond.
Detailed explanation-2: -Peptide bonds are amide bonds between the -carboxyl group of one amino acid and the -amino group of another (Fig. 3-1).
Detailed explanation-3: -Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
