In the context of proteins, which term best describes “a long chain of amino acid molecules” linked by peptide bonds?
A
Triglyceride
B
Nucleotide
C
Polypeptide
D
Monosaccharide
Verified step by step guidance1
Understand the basic building blocks of biological macromolecules: amino acids are the monomers that make up proteins.
Recognize that amino acids are linked together by peptide bonds to form longer chains.
Recall that a single amino acid is called a residue, and when many amino acids are linked, the chain is called a polypeptide.
Differentiate between the other options: triglycerides are fats, nucleotides are the building blocks of nucleic acids, and monosaccharides are simple sugars.
Conclude that the term describing a long chain of amino acids linked by peptide bonds is 'polypeptide'.
