Peptides: what are they?

The word peptide refers to the structure of certain molecules. These molecules are made of chains of amino acids, but they are shorter than proteins. In biology peptides tend to be funcional: in particular they are used as messenger systems within and without of cells. 1000s of peptides have been discovered and studied, in animals and in humans. Many medications are peptides, for example Insulin or the famous Semaglutide commonly known by its brand name Ozempic(C).

Peptides used as medicines are either the actual peptide produced by the human body or one similiar enough to trigger the effect of the native human peptide. This is quite different to the pharmaceutical paradigm we have become used to since the chemical revolution of the early 20th century where medicines were largely molecules which blocked enzymes, and hence had a tendency to cause side effects.

Clinically peptides tend to enhance certain metabolic pathways, and can be used to increase protein synthesis, reduce inflamation, promote the production, growth, healing and migration of cells. As metabolic pathways tend to degrade with ageing and illness, peptides may be useful at reversing this decline.
