Peptides are made from amino acids, which alongside proteins, are the building blocks of life and are normally sourced from food. The human body uses amino acids to make proteins that help the body perform a wide range of functions, including breaking down food and repairing tissue.
When two amino acids connect, they become known as a di-peptide. Today, many biologists consider this moment to infer the ability of “biological information” to be transferred.
As the length of these amino-acid chains grow, the names change. When between 3 and 6, they are called ‘short-chain peptides’ (otherwise known as bioregulators), and as the length of amino-acids increases further they change from being called peptides, to being called proteins, and then on to hormones.
