Quizplus · Accepted Answer

A macromolecule with nitrogen-carbon-carbon repeats indicates the presence of amino acids in the molecule, making it a polypeptide. Bone tissue is predominantly composed of collagen, a protein that has a repeating pattern of glycine-proline-hydroxyproline, which are nitrogen-containing amino acids that form peptide bonds. Therefore, a macromolecule isolated from bone tissue with a nitrogen-carbon-carbon repeat is most likely a collagen polypeptide.
