Verified step by step guidance1
Understand the role of peptidases: Peptidases are enzymes that catalyze the hydrolysis of peptide bonds in proteins or peptides, breaking them down into smaller components.
Recall the structure of peptides: Peptides are chains of amino acids linked together by peptide bonds. These bonds are formed between the carboxyl group of one amino acid and the amino group of another.
Identify the products of peptide bond hydrolysis: When a peptidase breaks a peptide bond, the result is the release of individual amino acids or smaller peptide fragments, depending on the specificity of the enzyme.
Eliminate incorrect options: Monosaccharides are carbohydrates, fatty acids are components of lipids, and nucleotides are the building blocks of nucleic acids. None of these are related to peptide bond hydrolysis.
Conclude that the correct product of peptidase activity is amino acids, as they are the fundamental building blocks of peptides and proteins.
