Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bond formed between two amino acids that results in a water molecule being released is called ____
A
peptide bond
B
complete protein
C
dipeptide
D
nitrile bond
Explanation: 

Detailed explanation-1: -The bond formed between two amino acids by the elimination of a water molecule is called peptide linkage. A peptide linkage is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

Detailed explanation-2: -The linking of two amino acids entails the release of a water molecule. Hence, the process that links two amino acids together is called condensation. The condensation reaction is also called a dehydration reaction.

Detailed explanation-3: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. 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.

Detailed explanation-4: -A peptide bond is usually a covalent bond (CO-NH bond) and since the water molecule is eliminated it is considered as a dehydration process. Generally, this process occurs mostly between amino groups.

Detailed explanation-5: -A peptide bond is a chemical covalent bond that joins amino acids together to form proteins. A peptide bond occurs between a carbon atom of one amino acid with a nitrogen atom of the other amino acid by removing a hydroxyl group and a hydrogen atom to form a molecule of water.
