Peptides, The Main Article

Peptides have an interesting and somewhat paradoxical characteristic: while they are too large to see with the naked eye, yet too small to interact with other molecules, they are actually too large to bind with anything. The first chemical elements that showed up in the naturally occurring world were peptides. Peptides happen when a molecule contains two peptide residues bonded together at their head or tail end. Peptides can appear as simple single-celled units called peptides or as complex mixtures of different sized peptides called peptides. Check out for more articles.

Peptide Handling Guideline

Peptides have a number of interesting properties, most importantly among them being that peptides are very tightly coupled (like two parts touching) and that this coupling is highly non-covalent, that is, it does not break apart upon contact with other matter. Thus, peptides play important roles in a number of biological functions, including immunity, inflammation, neurotransmission, and tissue repair. In fact, it is quite amazing that amino acid residues can form peptides and that these peptides can undergo reactions that result in releasing amines and lysine into an adjoining compartment (amines and lysine are the major peptide pairs). The release of lysine by an amino acid sequence in the wrong sequence can, for example, lead to the formation of amines that are necessary for a particular reaction, without which biological activity is impossible.

Among the many uses of peptides is in the medical industry, especially in the area of immunology, where peptides can play a role in many aspects of immunity (this is also an area of research that I am involved in). The main article continues below this line. For those interested, I have many more articles on this topic.
