Question

between the carboxyl and alpha-amino groups of alpha-amino acids.
The primary structure of a protein refers to the specific linear sequence of amino acids linked together by peptide bonds, which are a type of amide linkage. This sequence determines the unique characteristics and function of each protein. The peptide bond is formed through a dehydration synthesis reaction between the carboxyl group of one amino acid and the alpha-amino group of another, resulting in the release of a water molecule. This process repeats to form long chains of amino acids, which are the basic structure of proteins.
