What Is a Tripeptide?

Tripeptide is composed of three amino acids connected by peptide bonds. For example, glutathione is a tripeptide composed of glutamic acid, cysteine, and glycine. It has anti-oxidant effects and integrated detoxification and other biological activities. It exists in almost every cell of the body. Proline (or hydroxyproline) plus a tripeptide composed of other amino acids is the basic building block of collagen, which can be obtained by proteolysis of collagen, and has a variety of biological activities such as calcium supplementation, anti-oxidation and anti-aging.

A tripeptide is a peptide consisting of three amino acids by adding peptide bonds. The exact nature and function of proteins is determined by the presence of amino acids and the order in which they appear. A simple example is a tripeptide glycine molecule made from either a 3-combination or two glycines and one alanine. Triglycine tripeptide can only have one structure: glycine-glycine. Other tripeptides may have a different order: glycine-alanine-glycine, glycine-glycine-alanine, alanine-glycine-glycine. Each one is a different molecule.
Examples of tripeptides are:
  • Eisenin (pGlu-Gln-Ala-OH) is an immunoactive peptide that is isolated from Japanese seaweed, and it is more commonly referred to as Arame
  • Blue copper (glycyl-L-histidyl-L-lysine) is a combination of human copper with wound healing and skin remodeling activity. It is used in anti-aging cosmetics and is more commonly called peptide copper peptide
  • Glutathione (-L glutamyl L-cysteinylglycine) is an important antioxidant in animal cells
  • Isoleucine-proline-proline (IPP) found in dairy products as ACE inhibitor
  • Leuceptin ( N -acetyl L-leucyl-L-leucyl-L-argininal) is a protease inhibitor, which also acts as an inhibitor protease
  • Melanostatin (Prolyl-Leucyl-Glycinamide) is a melanocyte hormone (MSH) that inhibits the release of the peptide hormone produced in the thalamus.
  • Ophthalmic acid (L-glutamyl L- - aminobutyryl-glycine) is glutathione isolated from the analog lens
  • Norophthalmic acid (L-glutamyl-alanyl-glycine) is an analog of glutathione (L-cysteine replaced by L-alanine) from the isolated lens
  • Thyrotropin-releasing hormone (TRH, thyroliberin or prorelin) (L-pyroglutamyl-L-histidinyl-L-prolinamide) is a peptide hormone that stimulates the release of thyroid-stimulating hormone and prolactin from the anterior pituitary
  • ACV (- (L-aminoadipyl) -L-Cys-D-Val) is a key precursor for penicillin and cephalosporin biosynthesis.
