Polypeptides are assembled from _____.

Polypeptides are assembled from _____.

a. hexoses

b. glycerol

c. nucleotides

d. proteins

e. amino acids

Answer: e. amino acids

Polypeptides, sometimes described as amino acid polymers, are long chains of amino acids bonded together through the formation of peptide bonds. Amino acids are the principal element of polypeptides and proteins.

When amino acids link together they create peptide bonds that form polypeptide chains. These polypeptide chains can further fold and group themselves up into very specific three-dimensional structures, producing proteins which vary in their functionality in the organisms.

The other options, for example, hexoses (a group of simple sugars), glycerol (a component of fats and lipids), nucleotides (the building blocks of nucleic acids), and proteins (completely and fully shaped polypeptide chains), are not the fundamental units used for peptide assembly.
