What are Peptides?

Peptide Science – Part 2

What is a peptide and how do peptides work?


what are peptides

To fully grasp what is a peptide you must drill down to the molecular level to learn first about what is a protein and what is an amino acid.

What are Peptides?

Peptides are shorter chains of amino acids. Some refer to them as “small proteins” for if there are less than 50 amino acids within a protein chain., they are ultimately renamed and referred to as peptides.

What are peptide hormones?

Peptide hormones are proteins that have endocrine (hormonal) functions. Some create metabolic performance enhancements by communicating with the body to trigger the release of Growth Hormone (GH) into the blood. When this occurs the benefit shows in our ability to readily build lean muscle and release stored fat.

What is a protein?
  • A protein is created out of a string of over 50 amino acids.
  • Proteins role within the body is critical to the maintenance of health
  • They do most of their work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
  • There are 20 different amino acids that can be combined to create a protein.
  • The sequence of amino acids determines the unique 3-dimensional structure of each protein alongside its specific function.
  • The role of protein is very important. It is responsible for building body tissue as well as in the manufacturing of hormones.  Proteins are a part of every cell, every tissue, and every organ in our bodies.

The proteins in our bodies are continually being broken down and replaced. The body stores carbohydrates and fats, but it does not store amino acids. There needs to be a daily consumption to help the body make new proteins. The protein that we ingest gets digested into amino acids. These can be used to replace the proteins broken down into our bodies.

The digestion and absorption of Protein

You wake up this morning and eat and egg for breakfast. Let us follow the journey of this protein through the body.

The egg gets swallowed. Enzymes come in and break the protein into amino acids. The free amino acids recombine various ways forming what is known as “specialised proteins”. Specialised proteins can turn into some things i.e.) enzymes, antibodies, hormones. They also might end up as a structural protein., such as collagen which can occur in connective tissue.

Large protein molecules break down in a few different ways. 

  • Protein digestion starts in the stomach.
  • An enzyme called pepsin is the known protein-digesting enzyme of the stomach.
  • When pepsin acts on a protein molecule, it eliminates the bonds holding the protein molecule together.
  • These peptide bonds, once broken result in chains of amino acids that are linked together called “polypeptides”.
  • As polypeptides, they move into the small intestine for the completion of the digestion process.
  • In the small intestine, pancreatic enzymes by the name of trypsin, chymotrypsin, and carboxypeptidase finalise this breakdown.
  • These proteins are introduced via the duodenum via the pancreatic duct.
  • These pancreatic enzymes are helped by additional enzymes that are located within the microvilli of the small intestine.
  • The peptide bonds continue to be broken down therein resulting in what we fondly call “peptides”.
  • Peptides are two or more amino acids linked together. The enzymes will continue to break down polypeptides and peptides into amino acids.
  • The amino acids are tiny and have the ability to absorb through the small intestine lining and enter back into the bloodstream.
  • Digested nutrients leaving the digestive tract will route over to the liver before it enters the bloodstream. The liver gets first dibs at the nutrients coming through the digestive tract.

Learn more about peptides: 

Clinical grade peptides are superior to research grade peptides for a multitude of reasons.

Peptides that are clinical grade and prescribed by a specialist hormone doctor will have specific dosing criteria and instructions that help limit peptide side effects.

Peptide ratings give a patient an understanding of what they can expect to benefit from the use of individual peptides. Though we are not legally permitted to divulge the peptide names within our Peptide Rating, access to this information and to learn more about peptides and their mechanism of action, a patient must qualify with a login entry.
