A tripeptide is a molecule made up of three amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins, and when they combine in specific sequences, they can perform various biological functions. Tripeptides can be found in many proteins and play essential roles in processes such as metabolism and cell signaling. Tripeptides can be formed through the process of protein digestion or synthesized in the body. They are important in nutrition and can be found in dietary sources like meat, fish, and dairy products. Additionally, some tripeptides have been studied for their potential health benefits, including antioxidant and anti-inflammatory properties.
