A peptide bond is formed between
Correct answer: D. A carboxyl group and an amino group
- A. An aldehyde group and an amino group
- B. An aldehyde group and a carboxyl group
- C. An aldehyde group and an ester group
- D. A carboxyl group and an amino group
Explanation
A peptide bond is a covalent bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid. This reaction occurs through a dehydration synthesis process, where a molecule of water is released. The incorrect options all include an aldehyde group, which is not involved in peptide bond formation. Peptide bonds specifically involve the carboxyl and amino groups of amino acids.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
