Verified step by step guidance

Understand the primary structure of a protein: The primary structure refers to the linear sequence of amino acids in a polypeptide chain, which is determined by covalent bonds between amino acids.

Recall the type of bond that links amino acids: Amino acids are joined together by peptide bonds, which are a type of covalent bond formed between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another.

Learn how peptide bonds are formed: Peptide bonds are created through a condensation reaction (dehydration synthesis), where a molecule of water is removed as the carboxyl group of one amino acid reacts with the amino group of another.

Differentiate peptide bonds from other bonds: Hydrogen bonds, ionic bonds, and disulfide bonds are important in higher levels of protein structure (secondary, tertiary, and quaternary), but they do not form the primary structure.

Conclude that peptide bonds are responsible for the primary structure of proteins, as they establish the sequence of amino acids in the polypeptide chain.
