Peptides*information. Peptides*are short polymers of amino acids linked by peptide bonds. They have the same peptide bonds as those in proteins, but are usually shorter in length. The shortest peptides are*called dipeptides. They consist of two amino acids joined by a single peptide bond. There can also be, tetrapipteds, pentapeptides, etc.

Peptides have an amino end*and a carboxyl end, unless they are cyclic peptides. A*polypeptide*is a single linear chain of amino acids bonded together by peptide bonds. Protein molecules consist of one or more polypeptides put together typically in a biologically functional way and sometimes have non-peptide groups attached. These non-peptide groups are called prosthetic groups*or*cofactors.

Peptides, by definition must maintain certain characteristics. One of*those*being that the peptide chains must be short enough to be made synthetically from the constituent amino acids. Then they are considered to be called peptides rather than proteins. However, with the advent of better synthetic techniques, peptides as long as hundreds of amino acids can be made, including full proteins like uniquitin. Native chemical ligation has given access to even longer proteins, so this convention of definition seems to be outdated.

Another definition places an informal dividing line at approximately 50 amino acids in length (some people claim shorter lengths). This definition is somewhat arbitrary. Long peptides, such as the amyloid beta peptide*linked to Alzheimer’s disease, can be considered proteins; and small proteins, such as insulin, can be considered peptides as well.

*In simple terms and in a way all athletes would understand –*Synthetic Growth Hormone*is a complete protein and 191 amino acid chain where as CJC1295 has a 30 amino acid peptide chain.

*To summarize*– Peptides are very new and regarded as modern preventative or wellness medicine. They are designed to do everything from generating cells, increase REM sleep, increase sex drive, bring body fat down and increase appetite. All of the functions of peptides are beneficial to wellness, increase performance and anti ageing.

Examples of peptides are;*GHRP6,*CJC1295 DAC,*Hexarelin,*Sermorelin
