BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Amino acids can be covalently joined together in a condensation reaction to form a dipeptide and water. The covalent bond between the amino acids is called a peptide bond and, for this reason, long chains of covalently bonded amino acids are called polypeptides.

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. From: Storing Digital Binary Data in Cellular DNA, 2020.

Detailed explanation-3: -A peptide bond is formed by a dehydration synthesis or reaction at a molecular level. This reaction is also known as a condensation reaction which usually occurs between amino acids. As depicted in the figure given below, two amino acids bond together to form a peptide bond by the dehydration synthesis.

Detailed explanation-4: -When two amino acids combine in a condensation reaction, a covalent bond forms between the carboxyl carbon of one amino acid and the amine nitrogen of the second amino acid.

Detailed explanation-5: -In organic chemistry, a peptide bond is an amide type of covalent chemical bond linking two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another, along a peptide or protein chain.
