Protein, peptide, and nucleic acid contain carbon-nitrogen bonds. Lipid and carbohydrate do not typically have carbon-nitrogen bonds.
Among the biomolecules listed, protein, peptide, and nucleic acid contain carbon-nitrogen (C-N) bonds.
Protein: Proteins are large molecules composed of amino acid chains.
The peptide bonds between adjacent amino acids form the backbone of the protein structure, and these bonds involve a carbon-nitrogen linkage.
Peptide: Peptides are short chains of amino acids linked by peptide bonds.
Like proteins, the peptide bonds within peptides also consist of a carbon-nitrogen bond.
Nucleic Acid: Both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are types of nucleic acids.
They contain nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
The linkage between the sugar and the nitrogenous base involves a carbon-nitrogen bond.
On the other hand, lipids and carbohydrates typically do not contain carbon-nitrogen bonds.
Lipids are composed mainly of carbon and hydrogen with a smaller proportion of oxygen, while carbohydrates consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio.
Proteins, peptides, and nucleic acids all have carbon-nitrogen bonds, whereas lipids and carbohydrates do not typically contain such bonds in their basic structures.
