👉 Peptones are a class of small organic molecules that have been identified as the building blocks for proteins, lipids, and nucleic acids. They play an important role in the structure and function of these biological macromolecules. Peptones are classified into three main types based on their chemical properties: acyl-peptones (peptide chains with a single amino acid), amide-peptones (peptide chains containing two or more amino acids), and cyclic peptide molecules.
