Peptide bond is present in proteins, not in lipids or nucleic acids.

Explanation:

Peptide bond is formed between amino group ( NH2) and carboxyl group ( COOH) of adjoining amino acids.

A protein molecule is a made up of large number of amino acids, arranged in a chain, bound by peptide bonds. Each amino acid has an amino group ( NH2) and a carboxyl group ( COOH) . NH2 group of one amino acid forms a peptide bond (NH-CO )with COOH group of next amino acid with the removal of H2O.
