These days, there are some supplements which consist of peptides as the main ingredients, like ghrp 6, for instance. However, those of you who are interested in buying the supplements need to know that there are several different classifications of peptides which they better know before buying the supplements. Thus, you will be able to avoid buying the wrong type of peptides. At least, two of the classifications are as follows:
Non-ribosomal peptides: This kind of peptides are constructed by enzymes that are distinct to each of the peptides than by the ribosome. Glutathione is the most common non-ribosomal peptide and it is a part of the antioxidant protection of the most aerobic organisms. The other non-ribosomal peptides are usually in plants, unicellular organisms, and fungi and are synthesized by modular enzyme complex called non-ribosomal peptide synthesis.
Peptide fragments: peptide fragment refers to a protein fragment that is used to identify or qualify the protein source. It is also often the enzymatic degradation products in the laboratory on samples of controlled, but it can also be some forensic samples which have been degraded by natural effects.
