Key Differences
Peptides are sequences of amino acids linked by peptide bonds, which are crucial in biological functions. Peptones, on the other hand, result from the hydrolysis of proteins and serve as a nutrient source in culture media.
Peptides can vary in length, from two amino acids (dipeptides) to much longer chains, but are generally shorter than proteins. Peptones are typically the product of enzymatic breakdown, often derived from animal proteins or plants.
The main role of peptides in the body includes hormone production, cellular function, and as building blocks for proteins. Peptones, however, are predominantly utilized in microbiological laboratories to nourish and cultivate bacteria.
Peptides are essential for various therapeutic and cosmetic products due to their functional properties. Peptones, on the other hand, play an indispensable role in scientific research, ensuring the growth of microorganisms.
Structurally, peptides are defined by their specific sequence of amino acids. Peptones lack such specific structure, being a mix of various peptides and amino acids resulting from protein breakdown.
