Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following identifies the number of water molecules needed to remove the amino acids from a polypeptide with 20 amino acids?
A
19
B
20
C
21
D
22
Explanation: 

Detailed explanation-1: -Answer and Explanation: The answer is 6 water molecules. The formation of a peptide bond is a condensation reaction where two amino acids condense together and form a peptide bond.

Detailed explanation-2: -Peptide bond: A covalent bond joining the -amino group of one amino acid to the carboxyl group of another with the loss of a water molecule.

Detailed explanation-3: -Following this pattern, we can conclude that the number of water molecules lost is equal to the number of amino acids joined together, minus 1.

Detailed explanation-4: -1 Answer. Between two amino acids, one water molecule is eliminated and a peptide bond is formed. When 500 amino acids are joined to form a polypeptide, 250 molecules of water will be removed.
