Peptones are short chains of amino acids that are derived from the digestion of proteins. They are formed when proteins are broken down by enzymes or acids, making them easier for organisms to absorb. Peptones are commonly used in laboratory settings, particularly in microbiology, as a nutrient source for growing bacteria and other microorganisms. In addition to their use in research, peptones are also found in various food products and supplements. They can enhance flavor and provide essential nutrients. Their ability to support growth makes them valuable in both scientific and culinary applications, contributing to the study of microorganisms and the development of fermented foods.
