Introduction to Proteins and Peptides

Proteins and peptides are essential biomolecules that play crucial roles in various biological processes. Proteins are large, complex molecules composed of amino acids linked together by peptide bonds. They are involved in almost every aspect of cell function, including catalyzing chemical reactions, transporting molecules, providing structural support, and regulating gene expression. Peptides, on the other hand, are shorter chains of amino acids. They can act as signaling molecules, hormones, or have specific biological activities. In the pharmaceutical, food, and cosmetic industries, proteins and peptides are highly valued for their potential therapeutic, nutritional, and functional properties.


In China, the market for proteins and peptides has been growing rapidly in recent years, driven by factors such as increasing consumer awareness of health and wellness, advancements in biotechnology, and a growing demand for high - quality ingredients.
