BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Peptide bonds are amide bonds between the -carboxyl group of one amino acid and the -amino group of another (Fig. 3-1). The result is a planar structure that is stabilized by resonance between the -carboxyl and -amino groups.

Detailed explanation-2: -A peptide bond, also referred to as an amide bond, is formed between the -nitrogen atom of one amino acid and the carbonyl carbon of a second (diagrammed below).

Detailed explanation-3: -A peptide bond is basically an amide-type of covalent chemical bond. This bond links two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another. This linkage is found along a peptide or protein chain.

Detailed explanation-4: -An amide bond is a peptide bond. However, amide is a term used in the context of small molecules while peptide is used in the context of polymers (like peptides and proteins)

Detailed explanation-5: -Amide linkages joining amino acids are called peptide bonds or peptide linkage. Structure (b) is correct representation of peptide linkage.
