What are polypeptides?

Peptides are compounds that are composed of amino acids and connected by peptide bonds. Usually, peptides are compounds composed of three or more amino acids that promote metabolism and regulate physiological functions. 1. Boost metabolism: Peptides help boost your body’s metabolism. The body helps maintain the balance of its internal environment by secreting active peptides. The human endocrine system contains active peptides, such as thyroxine and insulin, which help regulate the body’s metabolic function. 2. Regulate physiological functions: food proteins can be absorbed and used by the human body only when they are decomposed into amino acids and peptides in the body to promote growth and development, bone development and immune function. In addition, the nervous system and digestive system also contain substances containing peptides. Peptides are used in medicine to diagnose diseases and treat certain infectious diseases.
