Peptides, such as those in ghrp 6 is a molecule formed of two or more amino acids. If a number of amino acids are still below 50 molecules called peptides, but if more than 50 molecules called proteins. Amino acids linked to each other by peptide bonds. Peptide bonds occur if one of the nitrogen atoms in the amino acid binds to the carboxyl group of another amino acid. Peptide present in every living being and a role in several biochemical activities. Peptides can be enzymes, hormones, antibiotics, and receptors.

The shortest peptide is a dipeptide, which is composed of two amino acids joined by peptide bonds single. There is also a tripeptide, tetrapeptides, pentapeptides, etc. A peptide having the amino end and the carboxyl terminus. A polypeptide is a single linear chain of amino acids bound together by peptide bonds. A protein molecule consists of one or more polypeptides are assembled and normally functioning biological and sometimes have groups of non-peptide attached, which can be called a prosthetic group or cofactor.

All the animals of the universe have peptides in their bodies in different ways, so that the peptide is one of the construction blocks of life. Proteins and peptides serve many possibilities, and many molecular biologists spent years researching the function of single peptides and proteins to learn more about how the body works.

Peptides can make a variety of uses in a person body, depending on which amino acids are involved. Some able to manage hormones, for example, while others take part in the function of antibiotics. Our bodies are also equipped to break down and reuse the peptide. If a person eats meat, enzymes in / intestine break down the protein in an amide bond to create a wide variety of peptides that can be digested or removed, depending on the needs of the body.

How the major classification Peptide?

– Milk peptide: They are formed from milk proteins by an enzymatic reaction that is broken down by digestive enzymes or by proteinase formed by the lactobacilli during fermentation of milk. Some milk peptides have proven to have an antihypertensive effect in animals and in clinical studies.

– Ribosomal peptide: is synthesised by translation of mRNA. It serves typically in higher organisms, such as hormones and signalling molecules. Some organisms produce peptide antibiotics.

– Non-ribosomal: This peptide is assembled by enzymes that are precise to each other peptide, rather than by the ribosome. Glutathione is the most general non-ribosomal peptide, which is a component of the antioxidant defences of the most aerobic organisms. Non-ribosomal peptide synthesis is another non-ribosomal peptides that most common in unicellular organisms, fungi and plants and are synthesised by modular enzyme complex.
