Peptide

A peptide is a short chain of 2 to 50 amino acids linked by peptide bonds, which are formed by a condensation reaction, joining together through a covalent bond. Peptides are the building blocks of proteins, and a polypeptide is a longer, continuous, unbranched peptide chain. Peptides play an essential role in fundamental physiological processes and are necessary for many biochemical processes. They are naturally found in the body and can also be ingested through food and supplements. Peptides may provide various benefits such as pro-aging support, anti-inflammatory properties, and muscle-building effects. They are used in medications for conditions like type 2 diabetes, multiple sclerosis, and high blood pressure. Peptides are also used in dietary supplements and are claimed to help build muscle, boost weight and fat loss, and aid in muscle recovery. Due to their potential health benefits, many supplements are available that contain peptides derived from food or made synthetically. Peptides are also involved in cell signaling and act as immune modulators, and they are responsible for several important functions in human cells.
