Verified step by step guidance1
Understand the nature of peptide bonds: Peptide bonds are covalent bonds formed between the carboxyl group of one amino acid and the amino group of another amino acid.
Recognize that when amino acids are linked by peptide bonds, they form a chain called a polypeptide chain.
Recall that polypeptide chains fold and combine to form proteins, which are essential biomolecules in cells.
Differentiate polypeptides from other biomolecules: polysaccharides are made of sugar units, triglycerides are made of glycerol and fatty acids, and DNA is composed of nucleotides.
Conclude that the correct structure formed by amino acids linked by peptide bonds is a polypeptide (protein) chain.
