Question: 1 / 400

Chains of joined amino acids are known as:

Fatty acids

Polypeptide chains

Chains of joined amino acids are known as polypeptide chains because they are composed of multiple amino acids linked together by peptide bonds. Fatty acids (A) are a type of lipid molecule, not amino acids. Glycerol molecules (C) are a component of fats and oils, and nucleotide chains (D) are found in nucleic acids, such as DNA and RNA. These options are incorrect because they do not refer to the correct type of molecule. Only polypeptide chains (B) contain chains of joined amino acids.
