Collagen is a very important connective tissue in the human body, as it is essential for body’s elasticity and strength. It is found mainly in the skin, hair, nails, cartilage, bones and muscles. Collagen is a long chain of amino acids, and is the most abundant protein in the body. It it made of individual amino acids such as glycine, proline, hydroxyproline and arginine. Collagen’s molecule has a similar structure to the DNA molecule, the difference is that collagen has a triple helix instead of double. If we break down this structure of the molecule into smaller sections, we get the basic building blocks of collagen peptides. These structures make up more than 28 different types of collagen in the body.
